Between the Hotel zone and the Romantic zone (Old Vallarta) is the original and oldest part of town. Hotels start off on the north edge with Villa Premiere and end on the south side with Hotel Encino and Hotel Rio. Very few offer all-inclusive as it doesn't really make sense when you have gourmet restaurant options just walking out the hotel door.
Check out the Zone map if you don't know the general layout of the city, it's not hard at all as it all lies along the edge of the Banderas Bay in a north-south curve.
