Have narrowed our next trip down to Thailand or Malaysia.

Have been recommended to go to Khao Lak in Thailand and to stay at the Le
Meridien Resort.

I understand the diving is supposed to be world class here at the Similan
Islands but understand it is whole day trips. My wife doesn't dive but does
snorkel. Any recommendations?

Also contemplating going to Malysia or Borneo and are thinking about either
Datai Bay or Nexus Resort in Karambunai.

Anyone been to any of the above and have any feedback - would be most
appreciated.
