My favorite is Character Breakfast at the Grand Floridian, and I'm 24 and I still do that. Characters in attendance are usually Minnie, Goofy, Pluto, Chip and Dale, (I think maybe even Donald?), White Rabbit, Alice in Wonderland, Marry Poppins, and the Winnie the Pooh characters who are wonderful! The food is wonderful, it's one of the classier breakfasts available in WDW, and somehow it seems more fun each time. They sign autographs, take pictures, etc. Really fun!
