Booking a party in Grafton: the short checklist

  1. Book 3–4 weeks ahead — Saturday afternoons fill first. A Sunday-morning or weekday slot is easier to land and sometimes cheaper.
  2. Ask: exclusive use or shared floor? Some packages close the playground for your group; most give you a private party room while open play continues around you. Both work — just know which you're getting.
  3. Put grip socks on the invitation. Most venues require them for every child on the equipment, party guests included. Ask if they're included in the package or sold at the door.
  4. Sort the deposit and waivers early. Expect a deposit to hold the slot — check the refund and reschedule policy. If the venue has an online waiver, send the link with the invites so check-in isn't a paperwork line.
  5. Confirm the cake rules. Most venues let you bring your own cake; some charge for other outside food. Pizza add-ons are the standard route.
