Would it be better to travel to Magic Kingdom/Epcot in mid to late May or mid to late September? I'm mainly concerned with weather and how long the lines will be.
Early May isnt bad at all, but mid to end of October isnt bad either. Last couple of years it was HOT during the day mid October but the nights cooled off nicely and on some nights was perfect to hit the pool
I cannot speak for Sept.,but mid to late May is when we have taken the majority of our trips to Disney. I have found the crowds (except Memorial Day weekend),to be not too bad. The weather is also nice in May. We cannot do Sept. at all due to school schedule.
