If they want to go to bars, I'd aim near the Crescent St./Bishop area, maybe Le Nouvel Hotel? Rooms are about $99/night canadian. That would probably translate to pretty cheap in American dollars, and it's a pretty nice place.

This site says about $103, but if you search around, you can probably find cheaper.

I got a hotel really cheap in montreal. The travel lodge downtown was like $60 or $70 Canadian (with a little student discount). It was VERY VERY small but really.. what are you going to do there other than sleep? Its a big building and I am sure there are plenty of vacancies. Oh and it was a 3 minute walk from a big St. Hubert on st. Catherines

hey i really appreciate ur help, im gonna run this stuff by my friend and let u guys know wsup... sorry i couldn't respond earlier, i just couldn't get to a comptuter
