I booked online just a day before for transfer from airport to the Gran Puerto ferry terminal for 3 of us. I received confirmation email and instructions on how to locate the driver. Everything worked perfectly as described. The driver was waiting with their company name on a sign by the time we got out, which was about 15 mins earlier than I specified. That was impressive! He confirmed my name on his mobile device and was good to go. I was very satisfied and impressed with their timeliness and professional service. I will use Discovery Mundo again.
