The first time we went to Hilton Head was in February. We stayed at the Disney resort and ended up buying into DVC that weekend with HHI being our home resort. We lucked out and the weather was actually in the high 70's all weekend and absolutely gorgeous. Yes, there are things to do right at the resort: bike riding, we went on a boat tour and saw dolphins, lots of activities for the kids including a fun campfire at night. Enjoy!
