Canada Transfers vs USA Transfers
Canada transfers competes favorably with USA Transfers, and both are very good. We have a slight preference for Canada transfers. $55 round trip is the going rate for transfers between the airport and the Zona Hotelera. One-way transport from your hotel back to the airport may come in at less than half that price, if you pay in pesos. (Taxis have to pay an extra fee to pick up at the airport.)
If you are Canadian, Canada transfers has historically accepted Canadian dollars at par with US $. Not sure how long that will last.
