There was major ventilation issues in our room. Besides the fact that the PTAC vent slats had months worth of dust (when the dust starts absorbing oil from the air and is gummy that is a not good thing). We set the PTAC unit to fan, but it only randomly turned on in the night for an hour and then stopped - the room got so hot we had to open the balcony for air and Yonge/Dundas in Toronto is a 24/7 party all year round, so loud! We didn't get a good night's sleep. I know we booked a smaller room, but considering this hotel is double what most economy hotels are, it was not worth the money. The only thing we really liked was the indoor water slide - that was super awesome! The teen arcade has machines that ate a third of our loonies without operating and was hot as hell being right beside the pool. We didn't go to the super expensive breakfast place - not when there are a zillion cheaper cafes right outside the entrances. Also, the hallways to the rooms have occasional hidden bumps I was constantly tripping on - what is up with that?
