We just got back... like most people here <lol> and we had gone to MK on Tuesday and only went on about 13 rides (may sound like alot, but when you count how many rides they have, it isn't as much as you would like to get in)
Epcot was no where near as bad. Went on Thurs. We went on everything we wanted to go on.... Mission:Space, Test Track, Universe of Energy Ride, The Land boat ride, etc...(basically every ride I beleive) including some little boat rides and a few shows in the countries, and were waiting around, shopping eating and such waiting for the Illuminations to start, and we also didn't get there when it opened., maybe about 11.
Went to Blizzard Beach Wed. and it wan't bad at all. Summit Plummet was an hour or so wait.
We have decided that we will not do MK during Sprink Break ever again, but might do MGM, Epcot, Animal Kingdom. Hope this helps yah!
