Translation of authorized in Spanish

There is a little problem: I can't go to Malaga to attend my course because it is fully booked, I have to go to Barca instead, which means I can't even go to there cause it is too far and the plane lands in the afternoon.
When we arrived at the port, or whatever it was, we were a little scared since the boats were very old and dirty. We entered the boats anyway and hoped for best. The boat driver started the engine.
From there we took the bus to the main gate of the Machu Picchu ruins. Unfortunately we had to take the train back the same evening.
