I would totally love to go on a cruise ship one day. 
Me too! I would love to go on a "Cruse to Nowhere" where the ship makes a 2-3 night trip without stopping at any ports on the way.
That does sound interesting.
Cruise ship
A cruise ship is a passenger ship used for pleasure voyages when the voyage itself, the ship's amenities, and sometimes the different destinations along the way (i.e., ports of call), form part of the passengers' experience. Transportation is not the only purpose of cruising, particularly on cruises that return passengers to their originating port (known as "closed-loop cruises"). On "cruises to nowhere" or "nowhere voyages", cruise ships make 2-to-3 night round trips without any ports
Cruise from the winter into the summer". It was a popular "cruise to nowhere", where a ship would depart Vladivostok, sail toward the equator, and come back without entering any foreign ports. Because of the absence of port calls, the trip required neither passport nor visas. It was known that the ship would pass within view of several foreign countries, and after studying its planned route, Kurilov decided that the best chance for an escape would be in the Philippine Sea, off the coast of Siargao Island
