We cruised back in January on the 3-day. We were able to dock at CC, but some of the excursions were cancelled because of the sea conditions. We had the Glass Bottom Boat reserved, but missed out because of cancellations. No big deal to us though...Maybe next time!
As far as the weather, it was warm, but the water was a little cool. I thought it was nice, because it wasn't too hot, but yet it was warm enough!
HTH!
