We have only taken one trip to WDW, traveling Wednesday to Wednesday. We are planning our next trip, tentatively for the last week in May. I'm thinking of flying in the Saturday of Memorial Day weekend and leaving the following Saturday. Arriving and leaving on a Wednesday (our trip was in early June) was a breeze. No lines at ME or check in. We did wait a bit for the bus to fill up before leaving the airport. We also had no issues on our way out. For you veterans with multiple trips under your belt... have you traveled on different days of the week, and did you see a difference? Is MCO crazy on Saturdays with Disney vacationers? Is ME or resort check in a hassle?
