...where inland (WDW) does not. Haven't been to HH at all yet, but expect frequent showers in summer months in FL.
At least with VB and HH, as opposed to WDW, you have water (pool & ocean) for your main attractions. Yes, it's hot, and yes, it IS humid, but vacation weather can be a crap-shoot anywhere, anytime.
I went to FL in the summer for the very first time last year, and figured I'd never do it again. Well, we're doing it again this year!!!. As it happened, it was hotter in NH than in FL while were were on vacation last year!
Have fun making your decision!
