This past easter was our first holiday trip. I havent been there any other holiday except valentines and fathers day so I cant help you with that, but I can tell you it was pretty crowded. My ds thought it was funny that there were actual lines just to get a fastpass and the fastpass return times were like 6 hours later, not good if park hopping was on your schedule. Alot of times busses were standing room only. I made all our ps well before we left. I even had a hard time getting chef mickey and could only get 8:30 pm one night. We planned to stay away from the MK on easter day. If you are staying onsite alot of the resorts have egg hunts for the little ones. Special brunches were at chef mickey and I think the swan and dolphin had something, but expensive. We went to epcot for the day. It was not too crowded, we did breakfast at cape may buffet, it was really crowded there, and at epcot they were pushing the alice in wonderland tea in england, i think its free but you had to sign up. I think they are doing something in epcot this year too. We went to mgm for dinner at hollywood and vine, that was totally packed and busy. If you plan well you will have a great time.
