I would HATE to stay in Patong! I stay in Karon, less then 15 minutes away with the bike!
I rent an little local house, don't get borred with hotel-employees, and Karon has a nicer bar-scene!
When I don't find the girl of my likings, take my bike and go for hunt in Patong, or even Kata. Take her back on the bike, if I like her let her stay longer, if I don't, start over next day!!!!
Had less trouble in general with the Karton girls! The one I had from Patong wanted more to go out with their friends at night!
