We went last year Feb 28-March 7th, and you couldn't ask for better weather. It was shorts, tanks, and sandals the whole trip! There was sunshine, humidity, and no rain for the entire time. We left NY in snow, with puffer coats on, crazy! Every night we did bring a sweatshirt for my ds (then 23 mos), but only used it once when he went to sleep during dinner at LTT. Good luck!
