What is required to reserve my party?

Parties must be reserved at least one week in advance and paid in full at the time of booking.  All payments must be processed in person at the ARC Center, located at 201 W. National St. in West Chicago.  Fill out our party request form and turn this form in at the ARC Center when reserving your party.   


Can I change the date/ cancel my party once it is reserved?

The package is non-refundable. Your fee can be transferred to book an alternate party date as long as there is at least one week’s notice given from your original party date. This must be discussed with the birthday party coordinator.  In the event of a one-time cancelation/change, 50% of the amount paid will be assessed for parties cancelled more than 4 weeks before the scheduled date. The remaining 50% can be applied towards a future birthday rental within a 6 month period. Cancelations/changes must be processed at the same time. No cancelations or changes can be made less than 4 weeks in advance. For character party choices, an additional $75 cancelation fee applies. 


When is my final food order and headcount due?

Food orders and headcount is due no later than the Monday prior to your party date at noon.


I would like more than 2 hours for my party. What are my options?

The party time slots are set up in order to allow adequate clean up/set up time between parties. In order to reserve additional time, you must book two separate birthday party time slots. If booking two back-to-back parties, your party will remain in the party room during the gap in between the timeslots.


My party is booked. When should I expect a confirmation e-mail?

Once your party is reserved, the birthday party coordinator will contact you via email 2-3 weeks prior to your party to remind you of your deadline to make any changes.

Party Guests

Yes, the fee for an additional participant is $5/person, This fee does not include additional food. Additional food items can be added on separately. Please see the party request form for details.


What if more or less participants (beyond my final headcount) end up attending my party?

Your assigned party attendant will take note of how many participants there are for your party. If there are more participants than your final headcount, your party attendant will make you aware of your final number of participants. The $5 fee for each additional participant will be due by the end of your party.  If less participants attend, you will receive a refund for any added on participants who did not attend. All refunds will be processed the week after your party.
