Peter, I visited their website and thought the same thing about the Montreal Hyatt (Regency). Are there 2 Hyatts in the city? As an aside, Gary Leff just visited the one you mentioned, Andaz, and reviewed in his blog
www.viewfromthewing.com not long ago. I've stayed at the Grand Hyatt in NYC booked on Priceline before as well at a great rate. I may Priceline a Montreal hotel as well, as I'm seeing on bidding for travel that people in August were getting 4* rooms at $80-90. Of course, one could end up with the Hyatt, but at a much better price.
