I have actually never been on a cruise ship. Have you?
No, but i have researched it online.  i think it would be thrilling to go on a pleasure ship, where you are not only visiting exciting destinations and ports of call, but also the ship itself is part of the whole experience.
What are some famous destinations or places cruise ships go on?
Well some ships go to Europe, those are for transportation.  But most cruises today and closed - loop voyage, that is, they end up where they began, so you really don't go anywhere.  Does that make any sense?  It looks silly now that i have said it.
