When I was in the pool today 5 middle aged Arab guys came in with there 20ish Thai girlfriends (sex workers). There were 5 men and 2 women so am not sure how those numbers work out. Later a third girl showed and one of the guys took her by the hand into a glass elevator up to his 4th floor room. Got to watch it all up close and personal from poolside. My hotel has a real mixture of types, I have seen many Thai families with very young children, middle aged Russians with older children, old age Indian couples and now these sex tourists.
