The one caveat that I will add to my earlier post is that with the VERY HOT girls, always set a search called Newbies because the longer they have been on that site, the more they know the intrinsic value of their asses. So I have gotten lucky with some newer to the website hotties and they have been up for meet and greets with little or no compensation. So if you are a "I want something for nothing" kind of guy, you are well served to have your default search start with newest registrants to SA first. Although only look at the first page as many register and never come back or have other profiles so you have to check activity.
As girls accumulate experience on the site, they will insist on a donation because they view uncompensated meet and greets as evidence of someone who is a "Time Waster." A lot of girls say in their profiles, "no Time Wasters", and what that is code for is "take your Splenda Daddy cheap ass and shove right up it the uncompensated meet and greets, as my ass has value and the guy who values it is gonna get it."
There is a lot of code in lots of profiles and I can decode it just as some can decode Morse and other codes. There is a language on SA that has to be learned.
As far as Montreal, I actually only ever met ladies on SA while on trips there and had sex with 1, as the other did not do it for me. Those ladies were cheap by standards of what I pay in USA but then again I pay more for escorts in the USA than Montreal and certainly have reason to expect the same with SBs.
