Yes Easter crowds. The reason why we are going. 3/31 to 4/14 in 2007
Hints:

Do AK and MK on early morings. They can get very crowded in the afternoon. EPCOT and Studio's can handle crowds better in the afternoon and evening.

Call WDW dining and do at least one ADR per day- Breakfast and lunch are the least expensive.You will know you have at least one meal in an air conditioned room.

A value resort suit will give you the space you need. You may also wnat to check out the Fort Wilderness Cabins -
