We were there over Spring Break 2005 and found that early EMH at MK were very very good. We were able to do everything we wanted to do (about 13 rides, Philharmagic, 6 characters-including the mouse himself, breakfast and a snack) all by 2pm. Then we went to Epcot. We went to AK for early EMH and I won't do it again, just about everyone runs right back to the Safari so we had to get FPs for that anyway. I don't know about Soarin' because it wasn't open when we were there. We didn't use early hours for MGM or Epcot, but we didn't feel it was necessary. We were at MGM for opening on a non EMH day and that worked out for us very nicely.
