I was in Phuket in April for 2 wks- Cant go that far without learning some MT-Fantastic- but the heat was killing.
Cant remember any names but I went to the following:
I did a training session at a gym located on the road in/ out of patong. The gym was upstairs above a bar- and there was a banner outside saying "we train muay thai"-
The trainer was quite hardcore so maybe thats him?? There was this French guy there who was staying in the same building.
The other session I did was on the road between Karon and kata? near the shooting range- this was a nice residential camp- which has a website
www.martialartsphuket.com.
The phuket stadium was building a training ring outside which I imagine is finished now.
