Early entry is offered on Mon, Tues, Thur and Saturday. As a guest of the hotel you should be able to use it any of those days you are there. However, that is not a published special, so it could change at any time.
Character meals:
Minnie and Friends- in DL at the Plaza. Its breakfast only. Its a served buffet (all you can eat, but there are people there to dish the food for you). We loved this character meal- the interaction was WONDERFUL. We saw Minnie, Pooh, Eeyore, Tigger, Chip and Dale, Hook, and the Fairy Godmother.
Princess meal at Ariels- at DCA. Lunch and Dinner. Its a menu, full service meal. You might a starter (soup or salad) entree and dessert. You'll see a variety of princesses, including Ariel with human legs rather then a fin. Book early for this meal, its hard to get seating at!
Goofys- DLH. Breakfast/ Brunch or dinner. All you can eat Buffet. Characters dance and come around for pictures. We saw Goofy, Donald, Aladin and Snow White in Oct. The interaction when we went was not that great. We've had better luck at the Plaza.
Chip and Dale at Storytellers- Grand CA hotel. Breakfast only. Menu or Buffet. Characters are a bit more laid back, and have a "woodsy" theme- Chip, Dale, Koda and Kenia from brother bear, meeko, and a forest ranger.
Lilo and Stitch at PP- breakfast only, menu or buffet. I've heard good things about the characters at this breakfast. Lilo, Stitch, Minnie and pluto are commonly seen. Sometimes Daisy Duck- she is rarely seen anywhere!
