Booking a party in Merrillville: the short checklist
- Book 3–4 weeks ahead — Saturday afternoons fill first. A Sunday-morning or weekday slot is easier to land and sometimes cheaper.
- Ask how the jump block works. Most packages are a jump-time block on the courts, then a private party room for pizza and cake. Find out whether your group jumps during regular open jump or gets reserved court time — both are common.
- Put grip socks on the invitation. Nearly every park requires them on the courts, party guests included. Some packages include a pair per jumper; at others they're a few dollars each at the desk — ask which.
- Sort the deposit and waivers early. Expect a deposit to hold the slot — check the refund and reschedule policy. Every jumper needs a signed waiver; send the park's online waiver link with the invites so check-in isn't a paperwork line.
- Confirm the cake rules. Most parks let you bring your own cake; some charge for other outside food. Pizza add-ons are the standard route, and a dedicated party host usually keeps the room on schedule.
