I've been to a couple of them. If you are looking for "7 Star" glitz and glamour then you're wasting your time and money.
Most of them are in unique locations and offer something different that you would never get at a "chain property". Most of all, you get impeccable personalized service.
Amangiri in Utah is a really special place and they will work with you to make sure you have a fully kosher 5 star trip. They wont charge a dollar extra for the Kosher (unless you want to bring a mashgiach) and know all the places to order meat/cheese etc from and will arrange new pots/pans etc and have a separate part of the kitchen set aside for kosher.
Feel free to PM me if you have an inquiry about a specific property....
