Booking Add-ons

All add-on party packages must be booked at least 14 days in advance in order to ensure all staff, supplies and materials are ready for your party. We cannot make exceptions to this. 

Party Timeline

The party areas are available to you only at the start time of your reservation. While 90 minutes might seem like a short amount of time, our birthday party package gives you and your guests admission to the Museum for the entire day.

If your reservation is early in the day, you may invite your guests to stay after party time to play in the Museum. If your reservation is later in the day, invite your guests to arrive early to play and set a time for guests to meet in the party area for food, activities and celebration.

PlayPal add-on activities (if reserved) will begin promptly 15 minutes after the reservation time begins (Ex: An add-on activity will start at 10:15am for a 10am party reservation).

Decorations

Less is more. We have found that the less set up there is, the less clean up there is. The Party areas were designed to be festive places to celebrate. Keeping it simple with decorative plates and napkins works great!

The Museum does offer add-on packages that include: PlayPal-facilitated programs, gift bags and Go Green! eco-friendly plates and utensils (more information here).

Decoration Policies:

  • Hosts may not tape, tack, or adhere anything to the walls or cabinets. We do have magnet boards in the room to hang cards or pictures.
  • Hosts may not bring balloons, inflatables, piñatas, glitter or confetti onto the premises.
  • A minimum $100 noncompliance fee will be assessed for failure to follow these guidelines.

Go Green! 

We encourage you to be environmentally friendly and consider the impact of what you bring into the Museum. Bring recyclable or reusable materials and take home much of what you bring.

Or, better yet! Less waste, less fuss!  The Museum can provide a colorful assortment of reusable utensils, plates, tablecloths and compostable napkins for 30-40 people (more information here).

  • $40 for a set of 30
  • $50 for a set of 40
