It is a question that is very difficult to give a straight answer, as it will depend on so many factors. Your wedding venue, how many guests you are inviting, the vendors your choose, where you are staying, etc. This is another reason I encourage couples to use a destination wedding planner in Mexico, it will take a huge weight off your shoulders.
