Anything in the mid-70s & up is perfect park weather, I leave on Wednesday and am looking forward to the weather that is forecasted!!! Would I like mid 80s, absolutely, would I like upper 80s and/or 90s, well i'd take them, but I don't love hot weather @ WDW...any weather is good weather when you are there though, why you ask? Because you ARE THERE!!! Enjoy!!
