Hi Dawn,
Sorry but the Crystal Palace in the Magic Kingdom is just the Winnie the Pooh characters and the Hollywood and Vine at Disney's Hollywood Studios just plays host to the Little Einsteins and Jo Jo's Circus characters. You'll be pleased to know there are many dining locations where you can find Mickey and pals.
The most popular place to dine with Mickey is at Chef Mickey's at the Contemporary Resort, this tends to also feature Minnie, Donald and Goofy but is subject to change.
Dinner at the Garden Grill in Epcot often has Mickey, Pluto, Chip & Dale and is a lovely family style meal that rotates through part of the Land ride.
Donald's Safari Breakfast at Tusker House in Disney's Animal Kingdom often features Mickey, Donald, Daisy and Goofy.
'Ohana at the Polynesian does a delicious breakfast and normally features Mickey, Pluto, Lilo and Stitch. The breakfast juice here is to die for!
I hope that gives you a few ideas, if you visit
www.allears.net click on dining then choose character meals/locations from the list on the left it will tell you about every character meal.
Have a great trip and make sure as soon as you decide where you'd like to dine you call 407-939-3463 up to 90 days in advance to book.
Jo
