I have never considered this but I actually did for our cruise in Nov. We live in CO, airfares roundtrip to Miami, we were looking at about $1100 for two of us. The cost with the promotion was adding $648 to our cruise price tag. It was going to save me about $350. I love a bargain! BUT you have to be very flexible in your travel times. We ultimately decided against it because are adding other travel plans to the trip. If you are flexible and cheap, I expect it can be a great deal.
