As several other reviews have mentioned, this hotel is super convenient if you have an early flight from the Calgary airport. I checked in early evening for a very early morning flight. The room was comfortable and quiet (so quiet that I was concerned I'd oversleep!). I had a couple of drinks in the lounge, which was really just your basic lounge. The prices were reasonable and service was good so I was happy. In the morning I was able to grab a cup of coffee on my way out the door.
If you have an early flight and don't want the drive from somewhere else in the city then I'd definitely recommend the Delta at the airport.More
