I found early EMH hours and MK to be absolutely essential, especially during Spring Break/Easter week 2005. We did not make use of any other EMH. I felt MGM and Epcot were quite manageable without using EMH. Early EMH at AK was a disaster. I blame this partly on the fact that we tried to use early EMH at AK on the Saturday before Easter. If we didn't have an ADR for Donald's we probably would have changed plans after waiting an hour for a bus because the buses were filling up at POFQ and other depots before arriving at ours. Once we got to AK, everyone was already making a mad dash for the Safari. At MK, people seemed to go to all different areas of the park. Over Spring Break, we arrived at MK at 6:50 for a 7:00am EMH, the park had been open until 3:00am the night before for late EMH. We were able to ride IASW, Peter Pan, Dumbo, see Philharmagic, saw at least 7 characters including autographs and pics, tea cups, raceway cars, eat breakfast, and ride Buzz by 10:30am. I think early EMH at MK is completely worth it. Hope that helps. Have a blast!
