FYI Peanuty468 - San Pancho or San Francisco is probably a lot further than 45 minutes north of PV. They like to seriously under estimate the travel time everywhere. It is north of Sayulita which is at least 45 minutes north of PV. I have been told it is a quaint fishing village (aka very small town). It will be perfect if that is what you want. If you or your guest will want a town with lots of clubs, resturants, and other amenities this may not be the best location. I don't want to scare you off because I have heard great things about San Pancho and really want to visit there on my next trip to the PV area.
Also, if your wedding is in the hot season May-Oct, you might want to consider finding some place with air conditioning. Trade winds can not be guaranteed to be constant and it gets awfully warm during those months even directly on the coast. It is not pleasant getting ready for your wedding while dripping in sweat. The door to my bathroom was closed the day of my wedding so my bathroom was very warm even though it was ocean front. We had a problem with our a/c one night and I don't think I could have spent another night without a/c. I would have had to go find a hotel room. It was miserable.
