Pros:
I've stayed at a few "neat" properties.
Got Gold Elite status after 10 nights as promised.
Often the cheapest chain in town. And decent for the price.
Frequent promos.
Locations can be quite good, big cities and resort areas.
Nice printed directory.
Bonus points when they goof up (ie: points don't post after a stay).

Cons:
Inconsistency among properties. Big time.
Too many promos are property specific.
Best avoided at interstate exits.
Properties change affiliation at the drop of a hat.
Program and elite recognition spotty.
