If you have an American Express Platinum or Centurion Card, it can "act" like a rewards program. Most Ritzs are on their Fine Hotels & Resorts listing. As a member, you get a complimentary room upgrade at check-in, free continental breakfast, guaranteed 4pm late check-out, and some other amenity at the hotel (such as free lunch, room credit, massage, etc.). Although you don't accumulate hotel points, you still get many of the perks as if you were a member of a hotel rewards program.
