You may either email reservations@hmns.org or fill out this interest form to begin the booking process. It is recommended that you book your party 4–6 weeks in advance. Parties are booked on a first-come basis, and full payment is preferred at the time of booking, but a non-refundable deposit of 50% of the party fee is due in order to confirm your party. If you book your party within a month of the party date, spaces may be unavailable and while we will try to accommodate any additional services or amenities, we cannot guarantee availability. Changes to your party package can be made up to two weeks prior to the date of your party. Reservation Coordinators will be unable to make any changes after that time. All birthday parties must be fully paid two weeks prior to the date of the party. Failure to do so will result in the birthday party being cancelled. If it is possible to accommodate any additional services that are requested on the date of the party, or if damages are incurred by a party group, these will be invoiced no later than the following week and due within 14 days of invoice.

Yes, you are welcome to bring in your own food or have it delivered, but there are some restrictions: no alcoholic beverages, no heating devices, and no full-scale catering. Please email us ahead of time with information regarding any deliveries you may be expecting. This will help us ensure your party goes smoothly!

Yes! To be eligible for the member discount you must be a current family level member or above, both at the time the reservation is made and at the time of the party. If you are not currently a member, we are happy to assist you with purchasing or renewing your membership at the time you make your reservation so you can receive the discount.

We can accommodate up to 30 people in a regular party room and up to 75 people in a large party room.

If there is space available, your party will be moved to a room large enough to accommodate all of your guests and you will be invoiced for the additional fee. If space is not available, up to 30 guests may remain in the booked space. Every child must have at least one caregiver. Additional guests will be free to tour the permanent exhibit halls, and you will be invoiced for their admission.
