Haha yes excellent plan I've had some outrageous parties this way...
I recommend two options depending on your budget:
(1) the best and most reliable way: make a booking at a high end KTV (Pimp, Czech, etc.) choose your girls from a lineup (make sure to indicate you want to take home, that will filter out some girls, and ask mamasan to recommend party girls), drink and play in the room for a while then pay the barfine to go back to your apartment. These girls are young, good looking, and love to drink and party. While in the KTV room you can decide to change girls if the chemistry is not right. You will need to pay for the room, drinks, girl fee, barfine, and tip the next day. All-in it'll be at least 10K baht per head.
(2) go to any go-go bar (nana, cowboy, patpong, etc.) and choose your girls. In this case it helps to choose one first, tell her you want to party together, then ask her to recommend other girls. She will choose her friends for better chemistry. It's a bit hit-and-miss as some will like to drink and party more than others (the go-go girls are mainly selling sex, vs. the KTV girls who are also selling the party experience). For this you should be spending 3-5k baht per head which is just barfine and tip.
