This isn't my normal type of travel at all, but I just want to go relax for a week at an all inclusive either in the PV area or Cancun area that is NOT noisy and on a swimmable beach. I'd prefer not to be surrounded by kids, no offense. Not looking for ultra high end. I want to go either at the end of this January or the beginning of February.

Check out the various 'Velas' properties for PV.

But there are quite a few other All-Inclusives and some are adults-only or at least have adults-only pool. Tons of information over on the Trip Advisor / Puerto Vallarta forum.

I am a frequent visitor to PV but I rent an apartment downtown.

bienvenidos/welcome, suze

Look into the Royal Hideaway Playacar. It is an smaller adults only AI on a great beach. Very quiet resort. You would fly into Cancun.
