Its been a long time since we went to Ariels, all I remember seeing is Ariel, of course, chip, dale and pluto, I do not remember seeing another princess as all actually.
At Minnies, which we did last April, we saw tons of characters!! Minnie, Mickey, Pooh, Eeyore, Tigger, Alice, Mad Hatter, Captn. Hook, Fairy Godmother, Chip and Dale, I think thats all, but there could easily have been more!! There were tons!!
We have been to goofys several times, some that I remember seeing there were Goofy, Max, Chip, Dale, Pluto, Baloo, Mad Hatter, Rafiki, thats all I can remember though!! I thought it was great to see Rafiki!! (I hear Timon can make an appearance at Chip n Dales in the GCH!)
HTH!!
