I think this is what my niece is doing this June. Her dance studio is taking a group June 23-25. From what my sister has said, the pick-up point is one of the All-Star resorts. The bus will take the girls, teacher, and my sister (she's an RN) who is acting as the groups nurse since several of the kids have severe allergies and require Epi pens. They have a late day practice the first day, practice and perform the 2nd day, then perform again the 3rd day. The description of the costumes sounds like Dorothy from the Wizard of Oz, checked outfit and red shoes. One performance is a parade on Main St, the other is in HS, but I don't know where. There was also some kind of dinner on the 4th day but my sister opted out of that. From what she was told, my sister will have to meet the bus at the All-Stars each day. She's not staying there, but they said they HAVE to ride the bus, they won't be able to meet the group at the backstage area of the parks. This is the ONLY reason my family is vacationing in June!
Oh, and my sister's only complaint is over tickets. The girls get a 3 day hopper with the dance package. She says the tickets can't be upgraded or saved for a future visit. We're staying for 8 days, so she now has to buy a 5 day ticket, when it would have been cheaper over-all for her to just purchase an 8 day ticket.
