I can confirm the Hacienda has a crew rate. I used to pay US$40 or $45 a night a few years ago for the cheap "west tower" rooms. For a little more, the south tower might be available. I wouldn't necessarily wait to the last minute to book. They have a "park, stay and ride" and sometimes groups that fill it up.

The diner is cheap, Starbucks and grocery store across the street.
It's not a 4 or 5 star, but rooms were clean and they always treated me well.
