Large resort in Marina Vallarta
While on the same trip to Puerto Vallarta, we also stayed at the Sheraton - so using that as a reference point... I liked the Westin much better. The Westin's rooms were much smaller (and had a very very hard concrete floor), but also very cozy and homey; there was not as much of a Mexican influence on the furnishings and decor of the room. The bathroom, on the other hand, was huge, which a separate tub and shower. All rooms seemed to have a small balcony over-looking the ocean. The grounds here are beautiful - all lush landscaping around the several pools. On our visit, the pools were very crowded, so we didn't venture in, and instead spent some time in the nice spa facilities. Marina Vallarta was a different feel from the Sheraton - it's a pocket of Puerto Vallarta that seemed to be row after row of resorts. Consequently, we found food prices to be more expensive at the Westin (and surrounding restaurants) than we did closer to downtown. While timeshares are a part of the property, this is the one place where we weren't approached to take a tour - a nice change! The Westin is also conveiently located near the airport, so if you're planning on staying put at the resort for awhile, there's no need to rent a car.
