Hi dht,
Hope you have a good trip in October. I read your post but don't quite understand exactly what you are after.
You say you want traditional thai massage, private rooms, but then you want nice ladies, and reasonable 'extras'.
Are you just using the TTM as a smoke screen for a 'quick blow' or 'cheap toss off'?
There are ladies on the beach who will do TTM, and then why don't you find some nice girl from a bar and rent a room for a couple of hours to 'massage the parts' the lady on the beach couldn't reach ?
I personally find TTM very rough and prefer a gentle oil massage. In this case, a wonderful oil 'toss off' from a 'nice' girl should only cost about 250 to 300 baht in a private cubicle.
I got a one for 100 baht once, but she was about 55 year old. The same age as my mother........ Best wank I ever had
Have fun
