Schools here get out in May and start back the 2nd week of August. Going in the summer, you can expect an afternoon thunder shower every day. Typically they only last about 30 minutes and really help to cool things down. Summer is hot, but there are plenty of air conditioned buildings to use for cooling off. Fast passes are a must to keep from standing in the hot lines. Epcot is the best park for beating the heat. They have the most indoor activities and lines there.
