I will be staying in Puerto Rico in July, in san juan. I want to go to Culebra for the day and want to fly because I heard taking a ferry is a pain. My fiancé and I want to spend the day at flamenco beach. What is the best place to fly out of, we would like to spend as much time at Culebra as will allow. Is it too much flying there and back in the same day, I'd rather not spend the night. Also how early should we be at the airport before the planes take off? Thanks in advance!
