I personally enjoy the Marriott quality and service at the hotels, particularily at the JW's. However, I have enjoyed the bonuses at the Hiltons, including both the Hilton AmEx card and the Hilton Visa. I just acheived the 50,000 bonus. I would love to switch to SPG, however, properties are limited where I travel. Unfortunately I travel to Detroit (I work for one of the big 3) and properties are limited for the Motor City. However, when i was staying at the Mexico City Sheraton while relocating to Mexico, I earned a lot of points, and all I can say is, Starwood is the easiest program for redeeming points. A couple of clicks and you are set. No expediting fees or anything of the sort.

As far as Hamptons go . . . I haven't found very many I feel comforatable in. Particularily the one in Warren Mi. You couldn't pay me to ever stay there again.

I guess as a seldom to medium traveler my preferences are:

Hilton, Marriott, SPG (only because of lack of properties in the US).
