We went last November and it was wonderful. However, the weather from day to day was very variable. One day we were swimming in the ocean and the next day we were collecting shells in long pants and jackets. We didn't do the dolphin cruise that trip but I'm pretty sure they still do it in November. The pool was warm enough for the hearty, i.e., the kids! It was a bit too brisk for me, but I'm cold-sensitive. The hot tub was nice though! Sorry I can't really comment on the restaurants. I remember wondering if it was going to be worth the trip before we got there, but as soon as we arrived, all of my worries disappeared. I just love it there.
Going back this weekend!!
