I seen him and Meg many times by the Big Hat at Disney-MGM Studios. I never seen them anywhere else. Usually we seen them around 11:00 to 2:30ish, on half-hour intrevals. If you are really lucky, Phil may be there, too!
BUT - I read on another site that some MGM characters may be meeting in the entrance area of MGM instead, but I have no idea if that is true or permanent thing or just a rumor!! Fortunately, the entrance and the Big Hat aren't far from eachother!
Every time we seen Hercules, he had real muscles, too!!!!!!!!
