I'm at OO. The hotels are pretty good. Lots of Hampton Inns, Double Trees, Courtyards, sometimesa Crown Plaza, a Westin or Intercontinental or Hyatt. I only know of one place where we stay at a La Quinta but it's a really small town that doesn't have much else. Locations are generally close to restaurants and things to do, depending on the length of the layover. The one hotel that most of the crews complained about was recently changed and it is definitely an improvement so the company listens.
As far as hotel points, we almost never get to keep the hotel points since the negotiated rate is so low. A couple holiday inns and Drury Inns have allowed me to keep the points but other than that, no dice.
Shuttle reliability is always very good. When a hotel doesn't provide a reliable shuttle or no shuttle, we either switch hotels or else we get a third party shuttle. Excercise rooms vary in quality but almost all the hotels have them.
