Taxi please
A taxi is best from the airport and quicker, approximately 15 min and about 8 miles. airport to Barcelo reception. I do not know the exact cost of the taxi fare from the airport. My response is similar to a previous post, do not expect to pay less than 100 pesos.
The public buses, gua-guas, run infrequently by the airport and if you do use them you would most likely have to change at the Beron crossroad for a bus going by the Bavaro Complex. The competition for available bus seats at the crossroad is heavy, a lot of the resort workers come from Higuey and they fill the buses, leaving the Beron locals waiting for a bus that can harbor them and it seems to never go by. Also the buses do not accomodate luggage very well. Once you arrive at Barcelo the bus would drop you at the gate and you would have to walk at least a half km from the gate to reception unless they opt to send up a transport to assist you. Cost about 20-30 pesos and hour(s) of heat and frustration.
Barcelo has a great complex and beach, enjoy your stay. Regards, PJT
