If you like water parks and nice hotels, visit the Great Wolf Lodge. The one I went to was in Scot Run, Pennsylvania. It is especially nice if you have kids. It is a gigantic place with tons of rooms, including quite large family rooms. It has an indoor water park, so you can enjoy that type of thing all year round. There are activities for kids as well as restaurants and spas for the adults. You can not only enjoy what the hotel has to offer, but you are in the Pocono mountains, so there are lots of other attractions in the area, both in winter and summer.
