It occurs to me that in short order, due to evolutionary changes in contemporary cruising, we might be subject to a completely different cruise experience, security wise, due to increasing global political unrest and subsequent dangers.

To be specific, how long is the cruise industry going to be able to regard checked luggage any differently than the TSA does carry on luggage on air-transports?

It's easy for the TSA to be more lenient with checked luggage on airline flights, for instance, relatively large volumes of liquids, firearms, other weapons and dangerous objects are allowed, since the passenger never comes in contact with their luggage while on the aircraft. Not so for cruise ships, every passenger is reunited with his/her luggage once in the cabin.

Would this development be a positive or a negative for you?
