At this point, there's none that I'm aware of.
In the past, I used to hear about something that I think was called the "Gainer House" (or something like that) which was near Seattle, or somewhere in Washington State.
But, a couple caveats. 1. It's not in operation anymore and hasn't been for years, the biggest one. 2. The primary focus and intent was on gay men from what I recall, not that they'd turn away straight men (which would be likely illegal) - kind of like a gay bar I suppose. I don't recall if they had accommodations for women.
Bottom line is, I don't know if there's enough demand to support such a thing.
That said, is there even much need for that? Cruise ship vacations and all-inclusive resorts exist, and from what I understand, the food is virtually endless. Order a drink package and you could pretty much have a drink in hand all day long.
I once heard a cruise ship employee almost swear the average tourist gained something like 0.5 to 1lb a day while there, and they're not even trying.
Only thing is, you'll probably need a passport. Very few cruise ship itineraries are all in the same country, and most countries don't appear to have any all-inclusive resorts at all from what I can tell.
