WHAT!?!?!?!?!?!??!?!?! My whole DW for 20 people, plus a reception for 175 people back in the States was $9,000! We didn't skimp at all (alcohol, food, etc)...granted, the reception was in Kansas and I'm sure things there are quite a bit more affordable there than on the coasts : )!
LAS CALETAS through Vallarta Adventures was definately the way to go! It's such a unique experience if you don't want to get married in the backyard (or back beach) of a big hotel. Plus, food, open bar, minister, wedding planner, and roundtrip boatride for you and your guests is included in the price! You can check out our wedding pics at the blog here to give you a little insight as to what you'd be in store for (for the money, that is):
