Siem Reap Map of Massage Brothels
There are absolutely loads of mini massage brothels in Siem Reap. Most will take $15 for a 20 year old. If you offer $15 and they insist on $20 or higher, tell them no thank you and prepare to leave. They'll accept the $15 most of the time.
The point circled in red is the massage brothel that the tuk tuks will take you to that's located closest to the Pub Street area. There were around 10 girls when I went and they were pretty. They quote $30 for short time and $70, maybe $60 for overnight at your hotel.
Top Town KTV has a large (30+) selection of girls. I'm pretty sure you can just walk in and take one for your hotel. There are no rooms in the KTV itself for play. The mamasan said it is $80 to take a girl until 1am, and $100 for overnight. There are various other KTVs around town and I'm pretty sure they all operate this way. I doubt you have to actually book a room and sing in order to get a girl.
