It's a lot easier VT man, and smarter to read through a bunch of the threads on clubs and agencies, then make a reasoned decision on your party's course of action than take one or two guys opinions. To take him to montreal for his final send off is one cool thing to do. Of course if it was my final send off, after a weekend in MTL I wouldn't be going at all. There is a thread somewhere about a previous bachelor party and the suite they rented for the night. Do a search for posts by bluebinary. Here is the info he sent me in a PM.

I negotiated with them, and ended up getting a Presidential Suite for $239.00 a night for 6 people.

I'm not sure if that's your cup of meat but a start.
Also strip clubs: A staple of any good Bachelor's party. From all of the posts I've read and members I know personally the consensus is: Cleopatra's for the best lap dances, Wandas for the best eye candy, and the Kingdom is a very nice club that has great looking women, though I can't attest to the mileage there.
Massage: besides all the info on merb, check out montrealmassage.ca. Kama is an amazing parlour, as is Isis. My favourite indy, Borrissa, started a spa, TSAR, and is totally legit, ie no HJ, But outstanding massage. There are so many others I want to try, just because of the research I've done.
Escorts: Since you're only there for a couple of days, I'd recommend you stay with the best agencies that are highly recommended in this board. For Indy's you can't and won't go wrong with, Cassey, Ronnie, Maria, or Anik. If you like Milfs or Cougars check out escortsplus or fortyplus. I think they are .coms.
I hope it helps. I know the friends of bachelor are going to have a great time. I hope also it doesn't fuck up the bachelors plans of going through with it. I only have one piece of advice for him: R U N... R U N.... R U N.... fast and far.
