Try
www.priceline.com You probably won't get any points, but if you bid for a 3*** property in downtown Montreal, you'll probably get the Marriott Reanaissance Parc. I got it for $45 USD per night during the FAQ.
Check Sheryl's great Priceline website for info, strategies and bonus money that will increase your bid at no cost to you.
