I was surprised to have never heard of this resort when it first came on to my radar via The Capitol Deal recently. It looked interesting, so I checked it out on the website and decided to give it a try. The resort is new and decorated with an understated elegance. The rooms were spacious and well appointed. We had a first floor terrace room and my only complaints were that the very tall landscaping was so close to the terrace, that we could not give our dogs a short walk via the terrace. I had assumed this is precisely why they required you to stay on the terrace level with your dogs. Also, the landscaping included several plants that are known to attract bees, and there was not shortage of them. I guess the upside compared to the balconies on higher floors is that there was more privacy. We just didn't use the terrace due to the closed in feeling and the bees. Also note that while they say they are dog friendly, and do provide nice dog beds and treats, you are not allowed to leave your dog alone in your room, and need to pay a hefty sum to a dog sitter if you don't have someone in your party who can stay with the dog.
In any case, the grounds of the resort are lovely, with a number of family friendly details - a big grassy lawn on which you can play croquet or other sports, large firepits with adirondack chairs surrounding them, a nice terrace on which you can sit and have a cocktail overlooking the grand lawn. There were many family friendly activities as well - e.g., zip lines, horse back riding.
The spa facility was very nice, beautifully designed with nice relaxation areas including an adults only pool. I was a bit disappointed in the massage I got particularly after specifically requesting someone very experienced and high rated. It wasn't bad. It was just okay.
The food in the restaurants was very good.
All in, It was fantastic in almost every way, to the point where I would be hard pressed to go all the way to The Homestead or The Greenbrier again, when the Salamander is just a little over an hour from DC.
