For Christmas of 2007, my family and I decided to do a two-week cruise. we've done other cruise lines, including Royal Caribbean, HAL, & Carnival. We heard from others that the Pearl was a decent ship and NCL is nice.
To do the 14 days, we had two different cruises. a five-day, and a nine-day. We had not ever done this, but it was pretty much what we expected.
At the time we did NCL, a very sickly stomach virus was very bad. Sanitation was extreme. Hence, the crew was tired and grouchy. The passengers were very international but friendly.
