Depends if you're company will spring for Fairmont or Motel 6. The former does have an outstanding program with Plat, IIRC, in as little as 10 nights. Some of the more mainstream programs, like Hilton HHonors, may be a little more flexible with transfers to FFP programs, etc. I was a Marriott silver for years but am unlikely to qualify and have switched over to HH more recently as they seem to want my business more.

Just some thoughts. Good luck and enjoy this silly game.
