We were there in May and had a great time. A few things:
Stay in the Zona Romantica. It is central and where you want to be. There are very nice places in the hotel zone, but it is just tooo far away.
We stayed at Vallarta Cora for a few nights and it was um, busy. If you're looking to let loose, that's the place to be. But we got a bit tired of it and moved to the Tropicana, a very nice hotel right on the beach and not far from Blue Chairs, but much nicer. We found a large, oceanfront room there with private balcony and kitchenette for ca. $79. But book it online and not at the hotel. We left the patio door open at night and fell asleep to the sound of the surf. It is not gay, but highly recommended.
Nearby are two excellent restaurants, la Palapa and Amapas. Amapas has world class food for a fraction of the price you'd pay in New York or Washington, though Palapas is great, too. Also try Red Cabbage, a cab ride away. Also very good.
Swede's, another popular restaurant in the Zona Romantica, is much over rated and unless you're A List gym bunnies, don't expect good service.
Have a great time!
