Weather Underground is saying 40% of tstorm on Monday and Tuesday. What's 40% translated to in terms of Floridian weather? We're planning to do MK on Monday and Epcot on Tuesday.
I vote MGM instead of Epcot. Both parks have most of their attractions inside, but the distance between pavillions / countries at Epcot means a real drenching as you run from M:S to Mexico!
If it were me, I'd go to MK anyway -- the rain may well drive some of the crowds away, meaning shorter lines. Most of my favorite attractions there are indoors anyway.
I would still go to M.K. anyway on Tuesday. It is supposedly the best day of the week to go as far as crowds go. If you go to another park it will still be raining there as well. If there is a chance of rain you will probably have very minimal crowds in the MK.
Any park except Animal Kingdom. I think maybe MGM. I like to take my time walking around the World showcase and enjoying the atmosphere of each country. I also enjoy the street performers. Then again they have performers at MGM. Just buy a poncho and enjoy. Hoping you have at least some sun!
I would just get ponchos and go to the MK. On our last trip it was pouring out but our clothes stayed relatively dry under the ponchos and crowds were nonexistent. We were able to ride splash mountain 3 times in a row with just our family in the boat.
