But a camping trip in mexico will save you on flight money. You can rent a car or jeep for cheap. Have fun on the beach and just go beach hoping. Bring beer. An keep 5 or 10 bucks in your pocket at all times so you can bribe the mexican police incase you get pulled over. "?Puedo pagar ahora?" Then show the 5 bucks. Usually works for me.
