Getaway resorts search

I’m searching for a nice spa/resort with a lot of privacy. A lot of the searching I’ve done seems to show me nice hotels with spa amenities, but what I’m looking for is more along the lines of Post Ranch Inn or San Ysidro Ranch.

Here’s what we like about those places: Very Private accommodations, No children, Spa amenities, In-room soaking tub, Nature to walk in, Great (and sometimes all-inclusive) food

Know any places like that?
