I'm looking at the same dates roughly and have been weighing up the various sites. For this my guess would be Sheraton or Omni, though neither of the options mention pet-friendly and I know both are...outside chance is chateau champlain but then perhaps it would list free internet...btw it went up to $140. If you do indeed make the booking please post your win as i'd like to know myself. Cheers.
Used the express deals option as I had believed it would be the Omni i'd be winning based on previous history, unfortunately it was Le Sheraton. I used the SPRING promo code to save 5% off the 88 dollars. Sorry accidentally put it as 5 star, its 4 star you should note.

I used the express deals option because I found a 10% off coupon which was: PLAYOFFS Ended up paying 206 pre tax minus 10% = about $93 a night. Worked out just as cheap as bidding I reckon.
Stayed here several times before, its a good price. Yes it needs modernization, but you get what you pay for...lots of restaurants nearby, good location, cheaper parking for MTL. To crash for a couple of nights it works great.
