Don't worry HH does not close down for the winter, Plenty of fine resturants and lots to do. Weather may be very nice though I doubt if you'll be swimming in the ocean. The pool is heated and the hot tub is open might need an extra towel for the walk back to your room. Programs run during the off seasons but you should check schedules daily. SC has some hot days and some cold days in Jan so it's anybody's guess as to which you'll get, unless it's real bad there is plenty to do in HH and the nearby cities such as Savana, Beufort and Charleston. Charleston is a little deceiving in that it looks close but takes atleast an 1 1/2 hours to get there. But well worth the trip IMO. Savana also is a very nice day trip. Unless you have trouble walking save your money on the bus pass and just get a good walking tour map. We bought a pass then got off on the third stop and never got back on. The ghost tour is fun.
