I LOVE WDW, but after spending last Easter AM at the MK I think I can safely say I would rather have my teeth drilled than to go back!! The park was closed really early, I honestly felt like I was drowning in people....you could not take 2 steps without colliding with someone and I was assaulted by about 4 giant stollers every 3 minutes!! We finally gave up and left about 11AM, and I felt like a dying salmon swimming upstream to spawn as we fought our way up mainstreet....we all gave an enormous sigh of relief when we finally got out of the crush of humanity. We went to EPCOT, which was pretty crowded, but NOTHING like the MK...talked to some people at the resort that night that said MGM had been packed and they went to AK, which was full, but not bursting also.
So my suggestion would be if you feel obligated to go Easter week, do MK earlier in the week and then hit AK, or EPCOT, or sleep in and avoid the parks altogether on Easter.
