The problem with character meals is that alot of the same characters there. Chip, Dale Minnie, Goofy, Pluto (and a variety of others which is dependant on who knows what) can be seen at Goofy's and Minnie's. Chip and Dale are also at Storytellers with Brother Bear and Tarzan characters. You'll see 5 princesses at Ariels. Lilo and Stitch, Daisy and Minnie plus Goofy can be seen at Lilo and Stitch. And Toy Story characters at the Round up celebration.
Some will say breakfast at Storytellers or Goofy's is the best food. I liked the different offerings at Lilo's for breakfast. We have always thought that Goofy's for dinner is much better than breakfast. They have awesome prime rib and cocktails!
But recently Ariel's changed their menu and their lunch and dinner are out of this world. But you are limited to princesses.
Don't know if this helps but it is an overall opinion from someone who did them all in November/December
Good Luck!
