There is so much to do in P.V. The city is beautiful, the shopping is great, there are amazing beaches, fabulous restaurants, and more. Which day of the week will you be in Puerto Vallarta.
We go to P.V. a lot and have stayed as long as a month at a time. In fact we're going in June for 10 nights. We generally go at least once each year.E-mail me with information about what you like to do and I'll try to make some suggestions based on your likes. You just can't see all of Puerto Vallarta in one day.
In Cabo you might want to take the glass bottom boat ride in the harbor or the kids might like the snorkelling tours. Bumming around town is okay too. We've only been to Cabo twice for one day so not much help here I'm afraid.
