We left our five year old son at the GF Mouseketeer Club last week while we dined at V&A. Although we stayed offsite, I made the reservation (with a credit card) when I made the reservation for the restaurant. It's in a small room next to Gasperilla's (sp) Grille, with 3 or 4 individual TV screens, beanbag chairs, tables and toys. The check-in and security procedure were reassuring.
Our little boy LOVED, LOVED, LOVED it! Not only did he get to watch his favorite movies and eat his favorite food, but he also had three different craft projects done for us when we returned to pick him up. Although I will probably let him try the Neverland Club if we eat at the GF, I wouldn't hesitate to leave him here again. You can't beat the size or individual attention.
