The beds are definitely horrid. I thought maybe I was being picky, but that is my only complaint about DI&S.

When DH heard me asking if it was okay to take an Aerobed through TSA, or if I should have it shipped to the hotel instead, we made the call that we won't be there again. Our first night there, my best friend and I were actually wondering if it would be softer to sleep on the floor than on the bed.... And for the record, I'm so not picky, LOL! My mattress before I got married was used by 4 other family members before me, and was probably 25 years old, and not top of the line, so I was used to bad mattresses! Theirs are just so hard!
The beds aren't anything fancy but I bring my own pillow and blanket because nothing is ever soft enough for me.
But they have amazing beds, beautiful grounds and amazing pools. 
My second oldest came down with a horrible high fever and we cut our trip short and checked out early. When they asked us why we told them we needed to get home to our daughter and they didn't charge for our last night.

We stayed at the Desert Inn & Suites for a week, just got back. AWESOME location! Closest we've ever been. To tell you the truth, I thought the beds were great. Did not hear any of the mattress noise mentioned on here. I always travel with my own pillow, but forgot it this time, and I thought the motel pillows were just fine. My issue was with the parking...there was NONE! Parking valets were very unhelpful. Although when I finally found a spot, days later...after valet parking...one of them volunteered to park our truck for me. He got a LARGE tip!
I think parking issues will be the only reason we try a different motel next trip.
