We really enjoyed our one night stay at Courtyard by Marriott Calgary South. We arrived a bit early and the front desk staff was very helpful in finding out how much longer our room would be, and even having it ready early! Our kids absolutely loved the pool and waterslide at this hotel, and we had it all to ourselves for several hours! The only improvements I could suggest are that the pool/hot tub could have been a little cleaner. Also, unfortunately, the pull-out sofa bed was very uncomfortable for the two family members in our group of 5 who tried it, so that would be something to know if you have a larger family like we do, and need the extra bed.
