We were in Sea and TDR in June. It poured the day we did Sea and overall we were there during "off" season week days. I remember seeing the following characters you could meet/take pictures with: (I am not counting characters from stage shows)
The Fab 5 in lots of costumes they don't have in the US Prince Eric, MAX ERIC's DOG!!!! (and OMG he signs!), Ariel, Genie, Berlioz, Toulouse and Marie from Aristocats, all 7 Dwarves, Alice, Rapunzel, Snow White, Tweedle Dum+Dee, Mad Hatter, the Fairy Godmother, Mary Poppins, Gepetto, Pinochio, Jimminy Cricket and I could have sworn Jack Sparrow was out, but my daughter wanted to eat instead of meeting him. There were definitely others, these are just the ones I am 100% sure of because I have pictures with them. In 2009, I met Indiana Jones in Sea which is pretty darn amazing in my book! lol A lot more characters and lot more unique characters come out imho. So if you are into characters TDR is the place to go. The only caveat I would say is meeting them unless it is a specific character line is a complete free for all. It's very different than in the US.
