If you are going to get into the action any want company don't worry about looks from the staff.It's NOT America where the PC people have driven good red blooded men into exile.Most guest houses along Ratutit Road are all GF and fairly cheap.One that my mates use is the Patong Street Inn which has just opened its new upmarket wing and has a large swimming pool.
Remember you are you -screw people and their stiff necked opinions.
