Using Priceline's 1 day sale today that adds $10 to my bid, I did a sequence of bids including $80 and $85 on 3 1/2 and 4*, none successful. I used both the Downtown zone and the Convention Center/Old Montreal zone. I then added 3* and kept the bid at $85 which was successful. With Priceline's addition my total bid was $95. The weekend following, 6/8 through 6/10, is Grand Prix Montreal which apparently brings in a lot of people.
