I think they are all going to be pretty crowded. I arrive that day, probably around 2 or 3, and have booked Epcot. I'm aware it will probably get more crowded at night because of the holiday but I'm hoping most of the schools and businesses are giving Good Friday off and not the Monday after so the holiday crowds will be leaving. I have an AP so if it gets too crowded, I'll just move on to another park.
