The Carnival Splendor is featured on the 7-night cruises and is one of Carnival's newest and best ships – even if you never get off the ship, you are on a great floating resort! And, the Carnival Splendor just had a $57 million investment after the engine room fire in November 2010 -- she is back in service as of February 2011 and is better than ever!
