I have never been in a cruise ship,have you? liner is a passenger ship used for pleasure voyages.
I was in a cruise  only when I was a kid.  Would you like to go in a cruise someday?
We have cruises to nowhere" or "nowhere voyages" where the ship makes 2–3 night round trips 
OK, so you just enjoy the ship, suppose it makes sense.  People always say you eat too much during a cruise because you are always having a meal, have yo heard it?
Really? Never heard of it ,except if their are lots of delicacy onboard
Maybe that is another reason eat a lot there, since food is included in the price.  Do you know what are the best cruises?
On a larger scale,we have the  Ocean liners also usually have larger capacities for fuel, food, and other stores for consumption on long voyages,  
What is the best known ocean liner? Just in case I plan a trip in a cruise.
