If you are thinking about cruising on the Norwegian Spirit I highly recommend you think twice. As a matter of fact don't even consider it.
My family and I (10 of us) cruised on the Norwegian Spirit July 20, 2008 to the Bahamas. 5 of us have cruised on other lines (Celebrity and Carnival) so we had past experiences to compare to the Spirit.

I had a inside stateroom and it was small! The staterooms on the Carnival are bigger.
