Was in Thailand for almost a couple of weeks with my SO, but in Koh Samui I managed to skip out 'for a walk' for a while and ventured to Lanai Beach area to see if I could get a massage. There are so many massage places everywhere but one trick is to look for ones that have a girl or two in casual clothes waiting outside vs. the traditionally, smart uniform that so many wear. They may also heckle you as you go by, which is of course a good sign too. I stopped by one that had two cute girls and inquired about the massage. After a few seconds they laughingly confirmed that they do a 'special' massage so I went inside and negotiated price for the pair of them - was 2,500 bhat or about $70 for 45 mins (no idea if that's high or low - likely could be lower if you had a nearby room/hotel as then no house fee for them to pay), but I only lasted about 20 mins (my fault really) and that was that. Still a nice bucket-list experience for me to cross out. Would be so good to be able to get a 4 hand massage for just $70 all in any time ;-) I look forward to the next visit to Thailand.
