It is what they call a hard ticket event, you will need to buy a party ticket if you want to go the party. The party starts at 7 and they will ask you to leave if you don't have a ticket, or if you want to save your park ticket you can get in with the party ticket at 4, at least that's been the practice in the past. We went last year and it was a lot of fun but I'm not sure we would take all of our kids only because it would be about 250 for the 6 of is to go. You can use it as a night out of the park. Maybe a character meal at The grand or a resort activity. Or if you were planing to do it the hoop dee do review, also expensive but so worth it in my opinion.
