We've tried Tusker, Crystal Palace, Ohana, and Hollywood and Vine.
Ranked in order:
1. Tusker House - 4 of the big 5, good food and good character interaction.
2. Hollywood and Vine - Food was decent, characters good.
3. Ohana - Different characters than many (Lilo and Stitch, Mickey, Pluto), food was pedestrian.
4. Crystal Palace - Character were the best part although it ook a long time for them to make their rounds, food was not good at all.
