I highly second the Fajita Republic....................the ruins are quite far from Nuevo and not like on other side....Canopy tours, ziplining are great especially the Los Veranos tour. A day trip into PV and a night trip maybe, walking and roaming the Malecon in PV to see the activity, shop , see the Sandcastles, etc. ( Sunday nights is best for activity). You could also go to the zoo on the south side of PV.......take a day trip to Bucerias, Sayulita, San Pancho. Roam around Nuevo Vallarta, and well the Mayan property is very large with parasailing, jet skis on beach, kayaking on site, train on site, beach, pool, etc. Lots to do in a week. The Mexican Fiesta offered on site, if you have been to one before well then I would pass, if you have never been to one, then you may find it interesting. Have a great trip.
