I had thought about it, but there's just too many properties in the US.

I use Choice as a reasonable alternative - that is, the price is usually right (I pay for my own) and generally all I need is a place to sleep for the night, some sort of decent breakfast, and a points/miles promotion to score on. I do no entertaining in the hotel. So, my requirements are price, security, and a reasonable degree of cleanliness.

If your personal standards are more toward Courtyard, Garden Inn, or full service property, you might be better served by the Clarion or Cambria line, or else move over to Hilton/Marriott.

Yes, I have run into the odd dodgy property or two, but bear in mind, I try to make every hotel stay mean something besides a receipt at the end of the day. That is, I'm following the promotions. So if an additional stay is needed for a big slug of points or miles, I just watch a little TV, screw around on the computer (they almost always have free wi-fi), read, and then crawl into bed. As long as the place is fit for human habitation, I'm OK.

The points and miles go to places that really are something special, and there I'm much more picky.
