Epcot is my least favorite of the Walt Disney World theme parks (though I last went in 1995, before the Animal Kingdom theme park opened). I went to Epcot and MGM the last two times I went to Walt Disney World (I had also gone to Disney World sometime earlier, but think I only went to The Magic Kingdom that time), and both times I spent the least amount of time at Epcot. It's not as interesting as MGM or The Magic Kingdom. And I hardly saw any Disney characters at Epcot either time (of coruse, the last time I was at Walt Disney World, I didn't see any characters very much).
However, Epcot does have some attractions that I like, including Honey, I Shrunk the Audience. I also saw a Lion King attraction about the environment. I forget the title of that. And I went on the imagination ride (I forget what it's caled now, but I've heard that it had Bily Barty as the voice of an animatronic character, who Dave Goelz later took over the role of).
