I stayed in a Parlor Suite (small room with couch/tv on outside, 2 Q on inside) last June 2011 for 3 nights at Desert Inn & Suites, and PVI in the 2Q/Kitchenette suite for 2 nights in August 2011.
I cannot recommend either, unless you are looking for a no-frills budget motel right near DL- the location of both are fabulous.
DI& S is super simple- think of it like Motel 6. I remember the beds being hard as rock- didn't sleep well. But I've also read posts here that say they are soft- so don't take my word exclusively. The elevator was a bummer- we were on the top floor with a stroller, so that was slow. Pool was awful- crowded and smelled like a ton of chlorine. Everything else was just super basic.
PVI has a F BBB rating (on a scale of A to F)- read them yourself, but note no claims in the past year. Still, I didn't like the room- it wasn't super clean, towels were thin, and lots of noise outside our room (we were on the first floor, with a walkway outside- there is no elevator and we had a stroller- if you can do the 2nd floor it would be quieter). The beds were fabulous.
Since those two stays, we have stayed at the Howard Johnson 5 times (Sept-11, Nov-11, Jan-12, April-12, May-12) and LOVE it. Its not the closest or cheapest, but I love that it feels more like a hotel than a motel.
