The coldest it usually gets at night in February is in the 50s maybe the 40s at the most. I think they heat the pool. I know they heat the one at the Beach Club. I think the best restaurant in that area is The Yachtsman Steakhouse at the the Yacht Club across the lake. The Flying Fish is really good too and it's right at the Boardwalk. Also check out Jellyrolls, it's a dueling piano bar at the Boardwalk. It's a lot of fun. I can't think of anything outside of the normal magic going on in February.
