Yes, agree, those 2 such places I used inside in Jomtien a few weeks ago were dreadful-much worse as what one can expect in BKK. Others say that taking the guy to your own HTLroom (if you stay closeby in those so often mentioned) cost the same (all charge 300 bt/ 1 hr /oil-which seems to be stdd all over Pty for about any place-Paradis charged more though).
SOme of the guys working Paradis/Btwn were also to be seen plying for custom later in the eve at Jomtien-may vary if they did not have enough custom in the day, I suppose.
Stayed at Zing myself and it still had an (always empty) work out fitness room. DK if extra charge needs to be paid to use it-even for HTLguests.
