I've stayed there many times, as a matter of fact this is my first trip to Las Vegas that I wont be staying there.
The Vintage Queen rooms are are small
(especially the bathrooms) but they're clean and comfortable and surprizingly quiet with super easy access to the parking garage! They're also the first rooms ever where I had to turn the A/C down! I set the thermostat on 50° and the room acually got cold! For the price you can't beat them! The Pavilion rooms are on top of the parking garage, again clean and comfortable and quite a bit larger if you're going to have someone with you. The Tower rooms are as nice as any place I've stayed! The Cabana Suites were new last year. Security is good and you need your room key to work the elevator. I recommend the El Cortez!
