On a scale of 1-10, crowds this past Easter week were a 9.95. The best time to go to the parks was early morning (take advantage of morning EMH) and very late (after 10:00). The nice thing was that the parks were open late every night and during evening EMH as late as 3:00am. Also, the weather was nice so even if you did have to wait a bit longer, at least you weren't standing out in the scorching heat. So, yes, it's extrememly crowded, but still manageable and still lots of fun. Good luck!
