I absolutely love character meals. Our favorite, right now, is Minnie's for the amount of characters. We have found the best interaction by booking the first seating for an inside table.
We enjoy Surf's Up also. Stitch is awesome!
I was not impressed with Ariel's at all. Bad service, very limited interaction.
I was not impressed with Storytellers either. Only three of the characters came to our table, two of which were Chip and Dale, who you can see at multiple character meals and many places in the parks.
Goofy's was a disappointment with the reduction in the number of characters. Now it is only Goofy at the photo station, Minnie, Pluto, and Chip and Dale.
