Interesting story, Blossom. Other than a bar bill, not sure what kind of extra costs they faced. Would be interesting to learn if the cruise line assisted with rebooking flights home.True cautionary tale:
My former supervisor at my job was on a cruise with her husband when Hurricane Harvey hit. Their ship couldn't dock, so they ended up stranded on the ship for an extra week. I don't know if they had travel insurance to cover any extra costs they incurred. Hopefully they did.
I would highly reconsider a cruise during hurricane season. Or at least be sure to have good insurance.
