We did a weekend there (no kids) about three years ago and it was great. The food was very good, and we enjoyed the spa. Even without the spa treatments, the indoor pool is terrific and your kids would probably love that. There are easy walking trails just across the front drive from the hotel, and they have a big fire pit outside for s'mores after dinner. I don't know about longer hikes, but if you're only going for one night, that might not matter. It's a lovely place.
