Yes, it is hot in early June, but not as hot as July or August. Plus, the earlier you go in the summer, the less likely it is you'll have to deal with a hurricane. Yes, it probably will rain almost every afternoon. But, boy, does that clear the place out! And, if you're like us and have to go when your kids are out of school, I'd much rather go in early June than at Christmas. On our trip in early June, the crowds were pretty manageable. Wish we were going with you!
