I'm not sure of times, but when I went in 2001, there were Star Wars parades, celebrity appearances, children could battle Darth Vader with a lightsabre and there were exhibits outside Star Tours, like an X-Wing and full-scale models of Artoo and C3P0
Also, lots of Star Wars character meet and greets, Star Wars-themed Who wants to be a Millionaire, trivia contests for adults and kids. Last year there were some talks by people involved in making the movies.
These events usually run through the day. I think they kick off with the Star Wars parade at around 11:00, and end at 6:00.
Jedi Mickey is located in the place where Fantasmic Mickey is at. It is one of the buildings on Mickey Avenue. My kids really enjoyed this special week. Don't forget to look up when you are entering the park becasue stormtroopers are everywhere!
Here is some info for this years stuff. I can't wait. We'll be there the first weekend. My SO is a huge SW fan so I'm sure we'll spend a bit of time there.
