Are things safe in PV?
I just returned from a long weekend in PV (my first time there). I used all local transportation (i.e. buses), walked where I wanted to walk, ate where I wanted and where the locals eat, etc. I seldom returned to the hotel until midnight or later (I didn't have a watch so I really don't know). My hotel was in the Romantic Zone (Los Arcos Suites -- highly recommended, good value for the money and is authentic Mexico!).
Yes, one afternoon (Saturday) on the beach not far from the Melecon (Boardwalk) at the local fishing pier section, a local guy who was somewhat inebriated himself, offered to secure for me whatever pleasure I wanted (i.e. drugs, women, etc.) in his broken English. Luckily I understood from another Mexican National who spoke fluent English, that he was arrested by the Tourist Police and I never saw him again.
The Tourist Police are a new idea in Mexico, to ensure the tourists feel comfortable. They have completely white uniforms (just like our US Navy) and usually a sidearm (9mm or Colt 45.... idk). There entire purpose is to keep the occasional out-of-step (drunk) local from pestering the tourists, both foreign tourists and Mexican National families on vacation. They do a very good job and are quite effective.
Never once did I feel uncomfortable while in PV at all. Don't put yourself into situations where you also wouldn't place yourself at home (i.e. you don't buy drugs and visit prostitutes at home, do you???). You probably won't be attending any local parties sponsored by one drug cartel/family or another, will you?
I would very highly recommend your going and enjoying your timeshare there without a second thought. PV is as safe as Mexico ever was, in my opinion. And although this was my first trip to PV, I have traveled extensively in Mexico (Mexico City D.F., Cuernavaca, Acapulco, Cancun, Cozumel, Monterrey, Reynosa, Ciudad Juarez, Nuevo Loredo, Tijuana, Morelia, Tulum, Chichen Izta, Matamoros), ALWAYS using the local (bus) transportation.
Que le vaya bien (May you travel well). Watching the local children diving off of the fishing pier, each trying to do a better trick than the previous child. There must have been 15 - 20 of them at one point, and then someone brought out a small exercise trampoline which the kids used to improve their tricks / dives even more. The must have ranged in age from 8 - 25, all with bright smiles, and calling out to each other while laughing, smiling and generally just being kids. The carefree life of a child, as it should be.
