Largest cruise ships in the world

To be honest, the world's 10 largest cruise ships are more like small cities than little schooners. The various dining options are plentiful, the spas offer every treatment imaginable and the theatrical entertainment is world-class. Plus, there are zip lines, casinos, pool deck movie screens and more on these massive boats. While it might be more difficult to find some peace and quiet on these gigantic ships, you can rest assured that your entertainment needs will most definitely be served. | Emily H. Bratcher
