I was helping someone book a Montreal hotel with flexible dates at the end of November. When I plug in the dates 11/24 to 11/27, I get a 4 star hotel for $95 with the following amenities: Restaurant, fitness, and business. This is likely the Hyatt. But, when I plug in the dates 11/26 to 11/29, I get a 4 star hotel for $100 with the above amenities along with a swimming pool. Could this also be the HYatt, and the reason that the swimming pool appears is that after a certain date (e.g. 11/25) that amenity is added? Thanks for your help.
