Zorro guy, I've been absent from this forum for some time, but I can give you some advice as I've been coming to LOS since '07 and actually living in BKK since last summer:
a) Don't make too many plans. These girls in the videos look ok, but once you get here you'll be overwhelmed by the number of lbs who are better-looking than them.
b) When it comes to ladyboys, focus only on BKK and Pattaya. Go to Phuket only as a change of pace for a couple of days, keeping in mind that it has become the no. 1 ripoff artist capital of Thailand. Frankly, one trip to Nana plaza (Cascades, or even outside strolling around) would be enough to keep you occupied for days, given the number of gorgeous lbs you'll meet.
edit: I just read your other post. Don't "advertise" that you make good money and pay well. If you look good, you'll get the ladyboys you want for a lot less than you thought.
