In general, temps will be pretty warm at the end of May. In the 80's during the day, cooler (but still warm) at night. Bring disposable poncho's since May is the beginning of the afternoon thunder storm season.
Sounds great! I was wondering this myself! Out of all the times I've been to WDW I've never gone in May. Sounds like a good time to go. Thanks for the info!
I also wanted to know about May weather, sounds like middle of May from what I have been reading is a good time to go. not too much rain and not to awfully hot yet.
We've taken 2 May trips to WDW. One was extremely hot....the other was a flood. So I guess all I can say is be prepared. You'll need something for the rain and probably something long sleeve in case the nights get a little cool for you.
