This business of booking hotels in Pattaya really is a bit tricky. I like most want to stay at a gay oriented hotel where I can bring my "boyfriends du jour" without problems. I want to avoid females and noisy Russians/Chinese. Of course a comfortable room is important and a pool is an advantage.
Probably the best plan in low season is to not book at all but to just walk into a likely hotel and assess the situation.
Last time I stayed in the Complex which was better than Boystown (Ambiance)as far as late night noise was concerned.
