I've not been this year certainly. The general attitude though works I think, whether patpong or other drinking places or wherever the SPs are hanging out. You could make an 'arrangement' but it's so much better to find one that clicks, stay at her place or take her on a short trip.
But as for the 'showing me around' thing mentioned by the OP, I don't honestly think that's a good idea. Better any decent guide book and go and see the sights, pretty easy. Most of them have zero interest in that and they can look an embarrassment walking round the Grand Wat or places. But take her down the coast to Hua Hin or somewhere with a beach to make her happy and she'll be better company. I know I'm generalising most Thai SPs are pretty generalisable. What do you think yourself southcoast?
Lazy, uneducated, impulsive harmful behaviour that borders on the insane, no interests or hobbies. Usually the 7 deadly sins rolled into one. Wait a few days and the mask falls off, they are usually a very good first few days though and they know their job in the bedroom department!
OP, look up the 3 day rule. You either end up having a shit time because she is a moron or she is too good to be true and things start to take a different path.
When you get on the ground you will be blown away by the choices on offer. You might meet some girl and she blows your mind, great service, funny, friendly, quirky, sweet almost and be taken away. That's what a lot of them are like though, so doin't get hung up on one.
If you do take a girl multiple days then remember you are the boss and once you have had enough you can send her on her way with her baht without feeling bad about it. It's always strictly business no matter how much she may suggest otherwise.
