We went last year (2004) the last full week of February. It was only 2 weeks earlier than we'd gone the year before. Surprisingly, for us, however, there was a BIG difference in the weather. No one was swimming. Even DH, who loves to golf, complained that it was too cold for him to enjoy golfing (which is almost unheard of-him not enjoy golf?!) I went on the Dolphin cruise and saw Dolphins, but it was definitely not worth freezing, which I did. Although they have activities, one day when we went to Pinckney Island, we came back early because everyone was so cold and miserable. This coming year we're going back mid-March again.
