We went in 1999 Easter week. We arrived the Saturday before (Palm Sunday weekend) and returned home on Easter. I vowed I'd never go Easter/holiday week again unless someone paid for my trip.
Saturday thru Wednesday were not bad. Thursday I noticed a presence of more people, Friday, even worse, Saturday...this is pre kids and we got engaged this trip so we still had life left in us... Anyways, that Saturday evening we went to the MK. Every line was long, every which way we turned there were tons of people. I had never left a park prior to closing before that trip.
So with that being said, if you are returning home the Wednesday before you should be fine.
Me however will be in Ft. Myers and I am dreading it. 2 yrs ago we were there Easter week and the crowds were horrid. This past April it was after Easter and heavenly. But 2017 it will be Easter week for us..blah!
