I'm glad you guys love one of the places that I have spent so much time at in my youth. I'm not from Puerto Vallarta originally, but I haven't lived that far from it as I'm from Guadalajara.
Anyhow, I'm living in the US now and haven't really gotten back to Mexico for a while now. And unfortunately, fishing is a sport that I have just recently gotten into, so I didn't have a chance to fish in Puerto Vallarta, but whenever I'm in Mexico again, I will make sure to do that.
I have something like that. A picture of me and my family in Mexico (from where I am from). I always have it in my wallet and I don't actually believe it brings me any luck and I never intended for it actually be my Lucky Charm, but I don't plan on ever throwing out this picture as it brings all kind of warm memories. So we can say, that this is indeed my Lucky Charm in some way, but I definitely don't treat it this way.
I think that for beginners any rod will do actually. You have to learn the basics first, so I wouldn't focus that much on its size unless you really want to specifically target only one type of fish, which I don't see a point in doing. To get the most of bass fishing though, I would say a shorter rod will be a much better choice. Remember though, that it's a subjective opinion and heavily depends on your preferences.
