If you want to meet characters - a great place to look is in the Animation building in Disney's Hollywood Studios on days when Fantasmic is playing. Because the characters are all in the park for the shows in the evening anyway, they like to spend their day in the air-conditioning in the Animation building. On a regular basis you can meet with Sorcerer Mickey in that area - but on Fantasmic days - you never know who you will run into! It's not as well known, so if you time it right, you can meet lots of characters and really spend quality time taking pictures with them and joking around! It's magical!
