Other questions? See our FAQ section below.
By reserving tickets to visit the Museum, you are agreeing to follow our health and safety guidelines, including:
Do not visit if you or anyone in your party is sick or experiencing symptoms of COVID-19
The Museum's play sessions are all "mask optional."
Leave your strollers at home or in the museum's coat room. We encourage you to bring your own front pack, or borrow one from the museum. Strollers on the exhibit floor are a safety hazard in the event of a fire.
Follow all safety signage in the museum.
Keep more than 6-feet physical distance from staff and other visitors not in your group.
No food or drink, other than water or baby bottles is permitted in the exhibits. We do have a small snack area for brief snacks during your visit. Breast feeding is always welcome.
For health code reasons, all visitors must wear some type of footwear inside the museum. Socks and bare feet are not allowed.
Adults are expected to help children follow the rules.
We ask that visitors stay with the individuals they are visiting with. A visitor group is defined as the 7 or fewer individuals you have reserved tickets for.
We reserve the right to refuse admission or ask people who are sick or not following the rules to leave the museum.
Nothing is more important to the Museum than the safety and security of its visitors and employees. The Museum prohibits any visitor, volunteer, employee, or other person from entering its property while carrying, possessing, or storing a weapon of any kind—including, but not limited to, a handgun, firearm, Mace, knife, or any other item which, in the Museum’s sole discretion, could be used as a weapon. This prohibition extends to all Museum property, including any space physically adjacent to the Museum, or at a Museum-sponsored event. This prohibition also applies regardless of whether the person is licensed to carry, possess, or store the weapon or whether the possession or storage of the weapon violates applicable law. The only exception to this policy is a law enforcement official duly authorized to carry such weapon(s).
Adults Without Children:
The Museum prohibits any adult who is not supervising, or accompanied by, a child from visiting the Museum during public operating hours, unless that person has received express authorization to do so from the Museum. If you’re interested in touring the Museum, please email our staff at email@example.com
Safe Space Policy:
CMNH fosters a culture of inclusion that promotes respect and celebrates diversity. We commit to making our facility and programs accessible and safe for all members of our community, regardless of race, ethnicity, faith, gender, sexual orientation, gender identity, or physical or mental disability.
The Museum will not tolerate harassment or disrespectful conduct of any kind. The Museum may refuse service to, or revoke access from, any person(s) threatening this safe, inclusive, and respectful environment. Behavior warranting such consequences includes, but is not limited to, verbal or physical harassment or discrimination against another patron, volunteer, or staff member, attempted theft or vandalism, or being under the influence of alcohol or drugs.
Are you still requiring masks?
All Museum play sessions are now "mask optional."
Do I really have to reserve/pre-pay for tickets before I arrive at the museum?
Yes please! We have worked really hard to keep each 3 hour play session to a manageable and safe number of individuals. We can't do that without your help with reserving and pre-paying. Pre-paying online means check-in is much faster, and even if you have a discount or are a member and aren't paying online, your reservation helps us keep control of the number of visitors.
How many people do you let in per play session?
We have capped the number of visitors for each 3-hour play session at no more than 50% of our capacity which is around 250 people.
I'm a Member, do I still have to make reservations? Yes please! To reserve member tickets, first create an account on our ticketing site with the same email you used to sign up for your membership (you only have to do this once). If you have already created an account, click "Sign in" at the top of the tickets page and sign in. Reserve your tickets (please choose the regular "Adult", "Child", "Senior" ticket types, NOT the ticket types labeled "Adult w/discount (will pay at door)") and then show your membership card when you arrive at the Museum.
If I'm a CMNH Member can't I just make reservations using the $0 "w/discount" price types?
Please don't. To reserve member tickets, first create an account on our ticketing site with the same email you used to sign up for your membership (you only have to register once). If you have already created an account, click "Sign in" at the top of the tickets page before adding anything to your cart. Reserve your tickets (please choose the regular "Adult", "Child", "Senior" ticket types, NOT the ticket types labeled "Adult w/discount (will pay at door)") and then show your membership card when you arrive at the Museum.
I couldn't remember my password, went to change it and now I'm locked out of my account! What do I do? If you get a message saying your account has been temporarily locked due to multiple failed logins, or for any other reason, don't panic! Use the reset password option to reset your password. Then clear your web browser's cache, cookies, and temporary internet files for all time (instead of just the past 24 hours for example). Then sign in again using the new password. If you don't choose the option of resetting your password, the lockout will last for only 30 minutes. Password Requirements: Must be at least 12 characters in length, contain at least one numeric and special character; contain at least one uppercase letter; cannot contain your name, username, or organization in any text direction; must be changed every 365 days.
If I have a Membership to another children's museum or science museum, that's the same as being a CMNH Member right?
Not really. If you have a membership to another ASTC or ACM museum, we consider that a "discount" so when you go to the ticketing page to reserve a visit to CMNH, please choose the "Discount" options (Adult w/discount, Child w/discount, Senior w/discount) and then show proof of your other membership when you arrive at CMNH.
When can I visit, and how much does admission cost?
The Museum is open for mask optional play sessions: Wednesdays through Saturdays from 9am-noon or 1pm; Tuesdays & Sundays, 9am-noon. Admission is $12.50 for adults and children aged 1 and older, $10.50 for seniors 65+, free for children under 12 months, and members. Your admission is good for one timed play session.
Do I just need to reserve one spot before I visit?
No, please reserve for the exact number of people attending. We use this information to limit the number of guests per play session, so don't just reserve one spot for yourself.
How far in advance can I reserve and pre-pay for tickets?
We release reservations up to 30 days at a time. Saturdays fill up quickly.
I have purchased or was gifted admission passes. How do I reserve my spots without paying admission again?
After you choose the date and time for your visit on our ticketing page, you will want to choose the price types called "w/discount", which will be a $0 reservation, just reserving your spots for that play session. Then when you arrive, please present your admission pass when checking in.
Is the museum accessible?
Yes it is! We have a ramp and an elevator to the second floor of the museum, and all the doors and restrooms can be opened using large push buttons. The second floor family restroom is equipped with an adult-sized changing cot. One-on-one aides or therapists are admitted for free when they visit with their client. Service animals are always welcome. Handicap accessible parking spaces are located alongside the museum on Washington Street. A ramp leads from the parking to our front door. If anyone in your group has sensory issues, we have noise dampening headphones available to borrow. We also offer monthly free "Exploring Our Way: Sensory Friendly Playtimes" for children on the autism spectrum or who struggle with sensory issues.
If I'm running late and can't get to the museum at the start of my reserved play session, what should I do?
Don't worry if you can't get to the museum right at the start of the session. If you have a reservation we will let you in anytime you arrive within that play session. Please just keep in mind that if you arrive late, your play time is limited and we will still ask all visitors to leave at the end of the session.
Do you really close the museum between play sessions?
Yes we do.
If we can't come on the date/time that we made reservations and pre-paid for what should we do? Email us at firstname.lastname@example.org as soon as you know you can't come during your scheduled visit. If you notify us before your play session begins and you either had to cancel because of a sick family member, or because you won't be in the area again to reschedule your visit, we may be able to refund you. Otherwise, we're happy to help you reschedule for another date/time.
I forgot to visit on the date I reserved tickets for...can I get a refund?
No, we're sorry. If you don't let us know that you can't visit prior to the start of your play session, we aren't able to give you a refund.
Why do I have to pre-pay online?
Pre-paying for your visit is becoming the standard for museums, and helps us keep the numbers of visitors per play session low. You must still make reservations even if you are a member or want to pay at the door with a discount.
Do you still offer Birthday Parties?
We are offering Sunday and Friday Birthday Parties and you can go here to learn more >>
What if I don't have internet access or for some other reason cannot make reservations online?
If for whatever reason you are unable to reserve your spot, please email us at email@example.com. If you need to speak to us over the phone, please call and leave a message at 603-742-2002. Please note that it is very hard for us to answer phone inquiries over the weekend.

Why can't I add enough tickets to my cart?
If you cannot add as many tickets to your cart as you'd like, that means there are fewer tickets available than you are requesting. Please select another date and/or time when available.
I was only able to reserve and pre-pay for one ticket for the day and time we want to visit, but there are three of us. Can I just add the other two people to my reservation when we arrive?
No. If there was only one ticket remaining when you reserved and pre-paid for tickets, that means there was only one spot left before we hit our maximum capacity. We have a very strict headcount limitation for health and safety purposes and will not be able to admit you with additional guests. Please reserve a different day or time, and please email us at firstname.lastname@example.org to release/refund that ticket.

Proof of any discounts will be checked when you arrive at the museum. If you don't see an email from the museum, please check your spam folder for an email from email@example.com.
Our plans have changed, or someone in our party is sick. Can I use my tickets for a different date and time?
No. We have a very strict headcount limitation for health and safety purposes.

If you notify us prior to your scheduled visit, we can help you reschedule to a different date and time up to two months after your initial reservation. Refunds will not be available unless a guest is unable to visit due to an illness, we are unable to reschedule your visit, AND you notify us in advance of your scheduled visit. Please email firstname.lastname@example.org.
I want to gift someone a few one-time use admission passes to the museum. Do you sell gift cards for that?
