Question

What are the oldest cruise ships still in operation?

Answer 1

I don't know the correct answer, but the Norwegian Dream is pretty old.  She was, at one point, taken out of commission, cut in half, and extended to meet current vacationer demands for cruising.  She is old, but she is beautiful.

Answer 2

Royal Caribbeans Soverigen of the Seas is from 1988 and is the oldest ship in the companys fleet.
