i've only ever been to Lamai gym in Koh Samui so cant really compare it to anywhere else although my boyf Matt has been to other gyms over there and he loves Lamai too.
every single morning session there have been 2 trainers to one person, Lukhim worked with me every single morning 3 plus hours and rungchai worked wiv matt constantly-even when working wiv your partner sparring etc the thai's were constantly jumping in, giving advice, correcting u etc. we also had privates most days (roughly7quid an hour)i always had Lukhim as i needed pushing to work hard and he was good at it and only one day he couldn't make my lesson (coz his father was ill) so Padeang took me instead and they tried 2 giv me the lesson free. the evenings are always buisier but even then Rungchai, Padeang, Hanarong, Noom, Nogweed, Lukhim were always there and always got round everyone, watching, correcting joining in with sparring etc.
as for the pad rounds, there was no getting out of them (believe me i tried) they hunt you down and will make you do a few but if you look too fucked they leave it at 2 or 3 rounds then let u go.
i aint got one word of complaint about any aspect of it-well looked after from beginning to end. its also in Koh Samui which is beautiful and is about 2mins away from Lamai beach. the trainers also involve u in everything, driving you to watch fights, eating with you etc.
