Hi WBC
To be honest i have only been to Koh Samet , Koh Chang .... and yes Phuket is an island to , right ??
After weeeeks of lovely ladieīs and mao to much to much (damned sangsom) in Pattaya you some time need to chill out

Koh Samet and Koh Chang are perfect in that case !
Both islands have great sand and water is clear and nice !
Old as i am i only go "pakalang" snorkeling and the captain had to drag me out of the water at Koh Chang 4-5 timeīs (another story)
Koh Samet has both quiet parts and some barlife , not like Pattaya/Phuket of cosī!
Koh Chang Same Same even if the barlife i saw was very poor .. 5 balloons and two twins under a steel roof and one of them picked up dog shit with her bare hands!
You remember witch one? i asked my friend ??
Nope he said and we left the bar for more booze at 7/11
Best thing with Koh Chang is the whole island is just a big hill , itīs a mountain sort of speak! Very nice and green even if they have had very little rain when i was there (feb-march-05)
Nice to ride motobike there but i suggest you donīt bring that much Sangsom cosī 45degree angle or more are for real here and itīs not only you driving there , belive me .. taxi driverīs like Sangsom to ! hehehe
