A Fantastic Experience All Around

This program is an absolutely amazing experience! Puerto Vallarta (PV) is a beautiful city with a rich cultural heritage that the people take advantage of.
First, the down sides (depending on your point of view). In some ways PV is akin to visiting the United States or Great Britain. It can be a bit more expensive than most of the rest of Mexico (especially if you're limited to visiting stores where the associates only speak English). In some ways, parts of the city are comparable to Disney World (according to my room mate when I was on the program). Finding inexpensive non-Mexican food is not easy to do.
Then again, you're not going to Mexico to eat expensive French food - you're there to experience the culture, the food, the life. The people are incredibly friendly, especially if you even try to speak a little Spanish to them (a simple "hola" and "Buenos dias" go a long way). The local food is fantastic, and you can get the best tacos I've ever had for about 12 pesos apiece (~0.75 USD). And that brings to mind the issue of money: "expensive" is all relative, and even in PV "expensive" is nothing compared to the United States or Europe (that said, it's easy to forget how much money you're spending in pesos).
The course itself was fantastic. Raul, the Academic Director, has been teaching ESL for about a decade and a half, and he's got stories you wouldn't believe. He's a great teacher. They've recently changed the TEFL books to make them even better. The owner, Alan, is very helpful and was able to assist me in finding employment; he has contacts everywhere in Mexico, and many overseas.
