Dated property, but large rooms, close to airport, don't let them force you into a room you didn't reserve
My trip started poorly when my flight got canceled because of maintenance issues and I had to spend six hours in the airport. Arrived in El Paso late, and when I checked in the staff at the check-in counter told me they did not have the room that I had reserved available (king size bed), but they were willing to give me a complimentary upgrade to a room. Intriguing... Then the other shoe dropped. The "upgraded room" was a two double size beds. I told her the "upgrade" sure didn't seem like an upgrade, and that I preferred a room with a king size bed. As if it were almost scripted she said, "but it is a very spacious room." I stood my ground and she miraculously found a king size room, but it was a handicapped room. She said, "the big drawback is there is no tub." I can't remember the last time I soaked in a bathtub. She gave me the key to the room, and off I went. Not a big deal, but it almost seemed like she didn't want me in the king size room.
In regards to the hotel, the property is pretty dated and the rooms show signs of wear and tear after 20 years. My room is extremely large and comfortable. In spite of being next door to the airport, you can barely hear the planes coming and going. Many restaurants are within walking distance. I didn't mind the sleep number bed, but I was exhausted. 
There are a couple different promotions out there if you join the "Carlson Club" before you make your reservation. Do an internet search and see if you can earn extra points or a free stay.
