I second a couple of FTers suggesting not to stay at a A-I. We were there like 3 years ago and staying at a small A-I resort called Qualcom, catering mostly to Mexicans. It wasn't the best food ever, but since it was a hotwire deal, we got a very cheap rate and did not mind going out for food. And it was the best decision, there were so many great restaurants in PV. One of the few things that I like, otherwise I was a little disappointed with PV.
Happy travels!
