I don't know about the Desert Palm. But, we just got back from 3 nights at the Desert Inn and Suites. Location is great - right across the street from main enterance.
Our room was clean. It's a very basic room. We paid $99 per night so I wasn't expecting anything more than a basic room so we weren't disappointed. I didn't have any trouble parking. It met our needs given that we were just there for sleep and showers.
Breakfast was just toast and pastries, OJ, milk and coffee.
Compared to the Park Place Best Western (stayed there last August), this was a bit nicer. The Candy Cane rooms and breakfast are better but the Desert Inn is a much quicker walk.
If you can get a good rate and are OK with very basic, but clean rooms, you'll be OK at the Desert Inn.
