My husband and I have been a few times and in May of 2000 we learned a little trick from this board. On some days (those that were EE for MK especially), we went to the other parks and vice versa. We found that the few times we did it were very beneficial. Epcot EE and AK EE were fine but if you switch and go to MGM on MK EE day and vice versa the crowds may be better - hope that helps!!
