there are lots to do in the typical touristy way. There is a small but enjoyable childrens museum(interactive play) and there is Costal discovery museum. There are the beaches and hokey shops and every type of resturant you can imagine. Savannah is just a about a 30 min drive in to georgia. There is Beaufort to tour grand old houses and take carraige rides about 30 mins. You can take Dolphin tours here that are great. If you have any more questions feel free to pm me.
December is a great time to come because it is not so full of people
