This doesn't exactly answer your question but I've booked those rooms twice and always got upgraded to the parlor suite (i think that's what it's called) with the 2Q + sofa bed in a separate room.
We don't stay at the Desert Inn anymore after a stay when they worked on our room while we were out without any notice and moved a bunch of our stuff around, an item was also removed from our room (my son's stuffed squid - of all things) and the front desk wasn't very helpful about it and our van got scratched in the parking lot (not the hotel's fault, I know, but just the icing on the cake). I have to say, I'm pretty bitter about the missing squid.
