Hi Andy, I’ve been to Thailand, but not diving. The Dolphin Queen from port Khao Lak offers the "Similan Safari", a 5 day 4 night for $630. They also offer nitrox. Are they any good, or should I look elsewhere? I’m thinking there’s more than a few dive shops around Pattaya so any help narrowing the list would be great. Thanks Steve sbwdiver@gmail.com
