I'll have to figure out how to PM for the spreadsheet, but in the meantime....
Here's our experience with character meals:
Liberty Tree Tavern dinner (Nov 05) - DD8&4 - familiar characters (M&M, Goofy, Pluto, C&D) - food is very basic, but very good - worked well for having one picky kid and a picky grandma along - characters were always coming by and Chip & Dale were absolute goofballs. Saw a few characters twice!
Crystal Palace dinner on T'giving (Nov 05) - DD8&4 - Pooh & gang is good for the younger set - still imposingly large for small people, but nice and furry - food was fantastic to boot. Oh, and there's a parade at the top of every hour for anyone celebrating a birthday. Honestly, I didn't know that going in, but my father, celebrating his 68th bday was a good sport and joined in.
Princess Breakfast at Norway (Nov 05) - DD8&4 - are there little girls going? 'Nuff said. Seriously though, we went for breakfast - food left a bit to be desired, nothing to write home about for the price, but you're not paying for great food, you're paying to see 5 princesses without having to stand in 5 lines. Meet&greets happened pretty quickly and you only saw each princess once.
Breakfastosaurus (twice!) - was great at old location, haven't been to new so I can't rate it
Chef Mickey's (June '07 DD9&5) - Is it possible to have more fun as a kid than to get up from the table and twirl your napkin over your head in the middle of dinner? I think not. Nice buffet, kids had fun with ice cream bar at dessert and the Mickey ear oreo concoction made my heart swoon.
I don't think you can go wrong with any choice you make. I'd go back and redo any of the ones I listed above.
Now, it's not character, but the dinner at O'hana was a whole lot of fun for our kids....coconut rolling and limbo. Good stuff.
