We sailed June 29-July 3 and the cruise director said it was the first cruise in 4 weeks (4 day Wonder) that didn't have any rain. It was wonderful. Yes it was hot but I hopped in the ocean to cool off! Plus I've been to WDW in June or July every year since 2000 so I expect it.
The whole family is cruising at the same time next year--3 of us are teachers, LOL, so we do what we have to do!
