I've stayed at the W Montreal many times...but not since COVID (so I do not what they are doing currently). I have been upgraded to WOW suites multiple times using SNAs. Previously, the Extreme WOW suites were not part of the upgrade pool for SNAs. Of course, that could have changed since COVID. The WOW and Extreme WOW suites are nice as they have outdoor balconies. This is a nice feature when the weather is good. Despite the name, I don't consider the Fantastic Suite to be an actual suite. Nothing about it feels like a suite... It's just a larger room.
