I'm going to Bangkok for about 5 days and wanted to get some diving in as a side trip. Any suggestions for a limited amount of time and easy transport in/out of Bangkok? Where is the best diving in Thailand? Is Phuket still good after the tsunami? What about departing out of Ranong? Is there some place with a fast train in/out of Bangkok? I was thinking about a 2 day liveaboard trip. What is the diving like compared to some place like Cozumel (which I've been to)? Thanks for the suggestions!
