I see the ferry only travels to Vieques twice on Sundays, 11am and 5pm. We are arriving in SJU on the 15th of December, and wanting to ferry over on the 16th on the 11am ferry. I'm concerned that with only 2 ferries that maybe we'll have a problem and get bumped? Does anyone know if Sunday's are a busy day for the locals to ferry back from the main island? Anyone have a gut instinct about this?
