Guests & Party Rooms

You may enter your party room 15 minutes prior to the scheduled start of your child’s party to set up. The party room must be vacated at the designated end time of your party to accommodate the next party. Party guests are welcome to enjoy the DoSeum until it closes.

Am I allowed to decorate the party room?

Absolutely. The DoSeum does not allow the use of confetti, glitter, or silly string in the party rooms. Guests must use painters’ tape when taping decorations to walls. Tacks, pushpins, and/or nails may not be used. Decorations cannot be hung from the ceiling, light fixtures or any other equipment mounted on the walls or ceiling.

Consider bringing an extra adult to help you decorate and set-up your room or to watch your children while you do so. Any damage to walls or fixtures will be charged to the guest.

Where do my guests and I check in for the birthday party?

Birthday parents/caregivers, please plan to check-in at the DoSeum's front desk 25 minutes before your party to allow for room set-up and decorating. Guests will also check-in at the front desk, and be directed to the 2nd floor, where they will register their attendance on a sign-in sheet for your party.

What if I have some adults attending the party that do not have children?

Adults are welcome to attend the birthday party and enjoy The DoSeum. We will ask unaccompanied adults to provide a valid state or federal id to conduct a short background check at The DoSeum’s front desk. Unaccompanied adults without ID will not be admitted.
