I just received an email from Brown's Private Services that is promoting a special price for Tripadvisor's readers on private airport transportation to Cabo area (zone 3). For a one way it is $80 and for a roundtrip it is $160. They seem to have very nice vehicles and well the photos of these look great. Have you ever tried them? I just made a reservation for an upcoming trip next month, so let's see how it turns out and I will keep you posted with my feedback. Oh and I almost forgot, they include bottled water and beer on board which is complimentary. (that was the best part lol).
