I would like to know the best way from SDQ to boca chica
35 bucks from the airport to Boca Chica, which is next door... quite expensive...even for the big smile
There are no buses that leave directly from the airport. If you are determined you can take a cab or motoconcho out to the autopista and flag down a bus from there. For around $20 you can just take a cab from the airport directly to the door of your hotel in about 20 minutes. Well worth the $20, especially if you have luggage.
$20 bucks it is for up to 4 passengers and as you said, "Well worth the $20".
