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 you 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.
All birthday parties must be fully paid 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.
The Museum is unable to offer parties on the following days: Thanksgiving, Christmas Eve, Christmas Day, New Year’s Day, Memorial Day, Labor Day and Independence Day.
Holiday weekends are especially busy for the Museum in general. If you book a party on these weekends, and we suggest that you and your guests plan to arrive early to allow enough time to find parking.
