We are at the Desert Inn & Suites right now (I type this from the room). Once again we have had a magical experience so far with this hotel. Upon check-in they upgraded us to a Parlor A suite. We love this room because you get an extra living room area to relax on the couch. We got here at around 11:00 yesterday and they let us check-in early and park our car in their lot and go to Disneyland. Our room wasn't ready yet so we left to go play and returned around 2:30 and we were given the suite. The staff has been great so far. I slept like a baby in the very firm bed.
Did you ask for the upgrade or did they just give it to you? We're going late March, and this would be great.
