Hi Grimsbyuk,
I left Patong about 2 weeks ago, after nearly 3 months in LOS, mostly spent in Patong. There were plenty of girls around. No problem there. BFs are normally 200 Baht in beer bars. "Tips" for the girls vary. If a girl is hot and wants 2000, you'll have a hard time negotiating a lower price unless you are pretty hot yourself.
If she is nice, but no stunner, she may ask 2000, but will settle for 1500. If she is just average, then she will most likely be happy to settle for 1000, and probably won't discuss money unless you bring it up.
With FLs in the discos, it is a bit different. The going rate there is 1000 Baht. Generally, my experience is that in the discos, if a girl doesn't like a guy, then she will just turn him down, and keep looking for a guy who meets her standards. If she goes with you, then it is because she likes you or figures that she can't pull much better than you, and it is 1000 Baht. I only had two ask 1500. One I gave it to, didn't attempt to negotiate a Baht, 20 yrs old and an absolute stunner. The other, I more or less laughed at, took a walk, came back and she grabbed me, said 1000 OK. She was very pretty, well better than average. If all else fails, you can always get a decent-looking girl at Safari, at 5 or 6 AM for 1000 Baht.
Those are all long-time prices. I never go short-time. But from what I've heard from the other guys, the price ranges from 500 to 1000 depending on the attractiveness of the girl, and how much she likes you.
Of course, if you prefer the gogo girls, then the prices are all higher than those quoted above. I would guess you could add 1000 Baht to the above. Didn't go with any gogos, so I can't say for sure.
All in all, I never paid over 1000 Baht after the first two weeks I was there. I never liked the disco scene much, but found that you can get some very nice girls there for only 1000, if you learn to play the game. I had some guys who are experts coaching me. Thanks, guys!
Hotels were definitely discounting substantially.
