We have been to HH twice in March. The first year the weather was beautiful. A little cool, but sunny, and since the pools were heated , we were able to use them. This past year, the temps were below normal for MArch -- 50's and 60's. We still enjoyed it, but it was definitely too cold for even a heated pool. There were a lot of folks out by the pools in bathing suits, but we were wearing long pants and jackets !
