There are several US Ritz Carlton hotels that I recommend based upon my club floor experiences:

Half Moon Bay
New Orleans (it's a bit of a maze to find the club, but it is the largest RC Club in the USA. It also has a very good spa)
Denver (great spa and access to an outstanding gym)
Philadelphia (excellent location and lots of history)
NY Battery Park (its' not as well situated as the one in midtown, but it's quite wonderful to see the Stature of Liberty from your room especially with the telescope provided). It's quiet on the weekend so you can always Uber to go uptown if necessary.
RC downtown Atlanta (it's the best hotel downtown...I know the RC Bulkhead is also quite nice, but my business meetings are always downtown. The club staff members are outstanding).
