It was quite confusing getting to the proper area to park and enter the hotel. Once we arrived and checked in/ got our room key, we were given instructions on where to park since we were leaving our car there for a week while we traveled. That was also complicated, however we appreciate the accommodation and it was convenient being attached to the airport. We got to our room and it was extremely hot, we turned the AC up to attempt to cool down the room, but were unsuccessful. We contacted the front desk and they did send a maintenance person, who was absolutely excellent. He acknowledged there was something wrong with the unit, however we needed to move rooms. We were not able to be accommodated on the same floor, but switching rooms in general was very frustrating at 10:30pm, when we already had a flight at 5:30am. We did get settled in another room, which the maintenance person did confirm the AC unit was functioning (which we appreciated), and we attempted to get some sleep. I have stayed in my fair share of hotels over the years, and these have got to be in the top 3 of worst, most uncomfortable beds there are. Overall, our experience was very poor and we will not be returning to a Marriott location.
