If you do go, you will love it! We have stayed there at least 4 times over the years for our own personal 2 - 3 day get-aways, never in winter though.
If you are not familiar with the area, there is a ton of things to do. In fair weather, local hiking around the Swallow Falls trails is beautiful. There are also two Frank Lloyd Wright homes to tour nearby, Falling Water and Kentuck Knob - BOTH are worth a visit. Nemacolin Woodlands is also less than an hour away.
Bottom line, even if you are not content to just stay cozy on property, there is plenty to pursue. Hope you enjoy!
