in Phuket you just create your own swinging party, it just depends on what your looking for!!!!!, although if you haven't been before there are some tricks to know
We were in Phuket last month and put an advert on Craiglist. Got quite a few seemingly genuine responses and met one couple who we had a great time with. You need to be aware of pic collectors, weirdos and guys with bar girls posing as couples but these usually stick out a mile anyway.
