I've got quite a few stamps from different countries and continents on my passports, and have concluded the following:
1) The world is full of places in better shape than the DR, infrastructure and economy-wise
2) There are very few places in the world where the women are more shapely than in DR.
Yes, yes, there are tons of other reasons to travel the world, and to love DR for that matter. But let's face it, the OP isn't likely in Thailand for the food (available everywhere) or the joy of learning The World's Most Counter-Intuitive Language (at least for westerners).
He's probably in that part of Asia for the the Asians. And if he likes Thai girls, he'll LOVE Dominican women. And we know he'll be loving them every chance he gets, quite likely. :bunny::bunny::bunny:
Some advice prior to arriving (other than the typical "learn spanish," which he's heard 100 times, and still probably won't do):
1) Learn how to make your favorite foods prior to arriving, and teach your maid/novia(s) whatever.
2) Understand that DR isn't all like any of the places you've lived before. It's a unique animal.
3) Relax and have fun. If you can handle the madness of Bangkok, SD should be a piece of cake. The same goes for less congested areas.
