KOH SAMET is a place i would not recomend staying overnight on , its overrun by mosquitos and is a malarial zone so unless you are taking a course of malaria tablets before arriving in pattaya then dont stay overnight.
THERE are closer islands to pattaya koh larn (coral island) is the closest it has lots of bungalows for overnight stays, also close to patts is koh si chang which is reachable by a ferry from si racha which is about 30 minutes from pattaya,
about 3 years ago i spent 3 days on koh si chang with 2 ladies had a great time !!!!!!
