And unfortunately the LTVA only allows tents within 500 ft. of one of the pit toilets. I know there's a toilet to the north of where we set up, but I don't know if we can stretch the rules to cover our area.
There's only one real motel in Quartzsite, a Super 8 near the west end of town. The Quartzsite Yacht Club (bar and restaurant) also has a half dozen or so motel rooms but both of these are virtually guaranteed to be full during that week, which is the peak of the Quartzsite season.
Blythe, CA is about 20 freeway miles west of Quartzite and has something like 30 motels of all types. It's about a half hour drive from the rally site on the LTVA. Be aware though, the weekend of January 14-16 is the annual Colorado River Bluegrass Festival which completely takes over the fairgrounds, so space may be tight over the weekend.
