I would like to tell you about mine and my wife's experience taking cruise on Norwegian Jewel January 9th January 18th, 2009 (Stateroom #9019, which we bought, but don't lived, and stateroom #5564 where we lived, but didn't buy).
Our troubles began when we arrived in Miami from Minneapolis, took transfer bus from airport to cruise terminal.
Terminal crew didn't allow us to go to the ship, with explanation that our booking is not in the system for this cruise. I showed them printed copy of all documents, as confirmation that we bought this cruise, but it wasn't enough. They told us that somebody canceled our cruise, and we should call to our agent in Minneapolis and talk with her. They asked us about colors of our suitcases, to pull them out of the ship. We were sitting at terminal for about 3 hours, before they finally let us know that it wasn't our error. We spent about an hour after that waiting for ship access. It was total 4 hours waiting time. We left home at 5a.m, and at 5p.m we finally went to the ship. All that time we were without food and water. Can you imagine what kind of feeling we had during these 4 hours?
