How will my guests know where to go?
Ask that your guests check in at the Museum’s Information Desk upon their arrival. Staff will direct them to the correct classroom.
The birthday family receives one parking permit to park in the Museum parking lot on the 4th Street NW side of the building. Please note that our parking lot is first come, first parked, and thus we cannot guarantee parking in our lot even with a parking pass.
After parking in the lot, enter the museum through the 4th Street/Employee entrance, then meet the Museum Teacher at the 4th Street Security Guard’s Desk where you can pick up your permit. Place the permit on the dashboard in your car.
The birthday party program will last two hours and include:
(30 minute set up prior to the party)
30 minute welcome activity and story time
45 minute building activity
45 minute period for birthday celebration (led by birthday family).
If you don’t have an accurate guest count until the day of the party you may pay for additional children on the day of the party. A staff person will contact you to confirm the party and answer any last questions. At that time, you will be asked to provide an estimate of how many children will attend.
