We go every year the week after Easter Sunday (starting 4/13/09) because we all work at schools. I recommend going early as a lot of the fastpasses for popular rides (Space Mtn) are gone before Noon. The parks are all open very late, and the MK will have a couple EMH until 3:00 am. There should be two showings of all the shows, so try and go to the later one. Make your dinner/lunch reservations as soon as your allowed. If you go to the waterparks, keep in mind that they often close because of capacity crowds by 11:00 am. I try and join TourGUideMike every year to get the Best Days at what Parks advice. Be prepared. GO early and leave by Noon, and then return early evening. Most of the stroller crowd are gone. There are a lot of older kids (10+) at this time of year, probably because of the school schedule.
