The Ritz yes, Ritz-Carlton the brand? It's hit and miss but it's quite good, I'd say the benchmark is Four Season Georges V in Paris, by far the best experience I've ever had.

That said, I stay in a lot of Marriott properties and I rarely use anything other than the room and interaction is pretty much check-in and check-out, quite hard to screw that up from a CS POV and as I don't pay myself, I care even less for anything just give me a bed please!
