We've seen him, Minnie and Pluto at the USA Pavilion at Epcot.
There were only a few other people around. It was great. We went from 1 to another in minutes.
We've seen other characters at Epcot, too with little or no wait. Sometimes they are hidden from the main walkway so many people must not realize they are there. I got a great photo of my DD's with Snow White, all 7 dwarfs and the Wicked Witch(all of them together) at the Germany Pavilion. Belle and Beast- Esmeralda & Quasimoto in France. The Aladdin characters in Morocco.
