Ariel is located right next to the Dumbo ride - usually a 20-45 minute wait during Easter week. Also, Toontown has (at least when we've been there) combinations of: Group 1 (Pooh, Eeyore, Piglet, and Tigger), Group 2 (Cinderella, Perla, Suzy), and Group 3 (Minnie Mouse, Chip, and Dale). Also, Mickey has a separate place to sign in Toontown. Pluto is often in the gazebo behind Minnie's house. You can see Goofy by his Barnstormer roller coaster off and on. Supposedly, Snow White is now making some appearances as well. They probably rotate a few other through there, but we've been 4 times in the past 3 years and those have been the characters we've seen. If you hang out at the entrance, you can get a bunch of others.
