Very good
The Marriot was the first and last accomodation on our roundtrip through the Southwest of the USA. Both times: good, clean and large rooms. Friendly and very helpful personnel. Free Shuttle transfer to and from LAX. The pool was good, too. 
One negative thing has to be mentioned: no free wifi in the rooms - only in the lobby. Therefor only four points. Free wifi should be standard - especially in a Marriott. 
We got great rates about 100 $ per night (DER TOUR).
Bonus: After the first night we enjoyed a fantastic sunrise from our room.
