In our case with transportation to the port in NY, we have an hour drive to the bus terminal and the bus would take us right to the port. I imagine that if it was a major storm that the bus would not go if there was a state of emergency. If that was the case I don't imagine most of the passengers would make the ship. I wonder if that ever happened????
I hear you about luck! We, for the most part have traveled to the Caribbean in October for the past 30 years on and off. We have never been hit by a hurricane. The day that hurricane Sandy hit NJ we just got off the ship coming from Bermuda. I shouldn't even say this out loud!
