I know people who were on a cruise in 2005 when Hurricane Katrina struck and last year to the date when Hurricane Isaac struck
I touched base with them recently and they confirmed they were staying home this year
Last year I was onboard the Carnival Freedom for an a 8 day smooth jazz cruise and our last 2 days we were in the middle of Sandy. Roughest water that I have ever been in and we were tossed out of our beds for both nights (we were in the very front of the ship in a 4J cabin)
Most folks don't think that a category 1 hurricane does not do alot of damage...it hung over my Parish for 2 days and destroyed over 50% of the homes here (mine was spared).
For my fellow cruisemates who are cruising between now and mid November, be safe and be flexible
