The nicest 5 star hotel I have stayed at is the Ritz-Carlton Laguna Nigel in CA. It sits atop a bluff overlooking the ocean. The views are especially breathtaking. The service and decor are fabulous. I think it only pays to stay at a 5 star hotel if it is in a great location. You’re paying for the location. Otherwise, I usually stay at 4 star hotels when I’m traveling.
