When I used to go to WDW at Easter, we generally spent that day at Epcot, because I feel that it generally handles crowds a little better than the other parks. Had a great day at Epcot a few years ago on Easter Sunday --- we did rope drop, and following a Touring Plans plan. Saw everything we wanted and did not have terrible lines, though we did have a bit of a wait for Test Track. The key for me going Easter week was to manage expectations. It was usually just my daughter and I, and we would pick about 4 must do's in each park, and figure everything else was a bonus. In actuality, by doing rope drop and using fast pass, we were generally able to do pretty much everything we wanted. Have fun!!
