6 May trips under my belt, most of them the first two weeks of the month. The crowds are easy to deal with. If you want to avoid any crowds, don't go to the parks on their designated early entry day. I have never had any crowding issues at Epcot except for Test Track. I assume Mission Space will be crowded most of the day. The Studios is easy if you go first thing in the morning and do Tower of Terror and RnR and the Little Mermaid. The rest is a breeze. The Animal Kingdom is fine. You can spend a liesurly day there and see most everything. The Magic Kingdom has been the most succeptable to crowding. It gets pretty busy on early entry day and is crowded on Saturdays. If the Fireworkds and Spectro Magic Parade are only showing on Saturday or the week end it will be crazy and get worse as the day goes on.
The weather has always been warm. A couple trips it was in the 90's every day. A couple trips veried from the low 80's to low 90's and a couple trips there were days in the high 70's to the high 80's. There has been little rain. But when it does rain it sure rains hard! Only once in the 6 trips did it really stop us from doing much and that was fro half an hour.
