We spent a wonderful night at Hillbrook. This place is expensive, but it is worth every penny. We stayed in one of the cottage rooms; it was wonderful: nicely decorated, with a comfy king-sized bed and jacuzzi tub. Dinner and the tavern were great as well.
I think the highlight of Hillbrook is the atmosphere; although it is conveniently close to Charles Town (wonderful to explore itself), it seems to be in the middle of the English countryside. Lots of wildlife and quiet and serene.
The staff goes out of their way to assure a good time; wonderful and attentive.
My only regret is we did not get to stay long enough!
