Ritz does track your stays and provides recognition, although nothing great. At my 20th stay I got a Silver/Metallic Insulated Coffee Mug with the Ritz-Boston Common logo. At my 25th stay I got a golf shirt from the Ritz San Francisco with the Ritz logo. Saw it in the gift shop for some outrageous price and wanted to return it for a credit, but my wife said that wouldn't be appropriate. At a stay at the DC location a few years ago we were upgraded to a suite which had been turned down for a guest who was a no-show the prior night. The pillow cases were personalized with his initials; not sure how many stays until you get to that point....
