Mr. Oblivious-
Make sure you get a spot in Haad Rin Nok. Do your research beforehand; a place close to the party is infinitely better for pulling than somewhere far away.
If you're going in a smaller group, or by yourself, you can just go without booking a hotel and find somewhere to rent once you're there. If you're renting while overseas though, you'll need to book a minimum of 7 nights - that's how those hotels maximize their incomes.
Do day game while you're there, too. Few guys do it, but while the party is good and you can pull here, daytime is even easier, and there's a lot less competition for the girls' attentions, even though they still WANT to party hard, and are sitting around waiting all day for the night time. Instead, you can bring the party to them before dusk, and really get the most out of your trip.
