We did spring break which fell during easter week for our 3 ds two years ago and will do it again this coming up year 06. I did read on the boards that it was busy, but really I am glad I was well prepared, I made all the dining reservations before we left. That was really important. All week long they said no walk ups at the popular places etc. It was good to have a decent meal without waiting on a long counter service line etc. The counter service lines were horrendous, from 11-3 it was nonstop. The buses were standing room only alot of places you went. There were actual lines to get a fastpass and the fastpass had return times like 6 hours later, this was not good if you wanted to park hop later on etc. My ds did not want to get up early so we usually spent later times at the parks etc. The weather was so much more bearable than in the hot summer, august, which we used to go to. I am glad we also brought alot of snacks into the parks because I just couldnt see waiting in a 20 people line for a turkey leg etc. On easter day we spent most of it at epcot and then headed to mgm for dinner. There was a big storm later so we went back to the room at the swan, but I think epcot was really uncrowded early in the morning., we were avoiding the mk at all costs on easter day, we did it earlier in the week etc. If you plan well you will have a good time.
