My 2 ds, ages 11 & 8, did the PC on Thanksgiving and loved it. Disney knew my oldest was turning 11 b4 the PC, but they said that was fine. He's disappointed that he'll be too old to go next time. They stopped at the Poly, CR, WL, and FW and came back with their loot and bandanas with name stickers. The CMs in the parks saw the bandanas, and they got extra attention. My boys were given pirate hats and swords by grandma, and the swords weren't allowed. They didn't take the hats because they didn't want to lose them. They had crustless pb&j and rice crispie treats for lunch. They weren't very descriptive about what happened, but they had a great time. I met a couple of moms from Disboards whose kids were on the same PC.
The PC isn't Peter Pan themed, so if you want that theming maybe you should look into the Neverland Club.
