Carnival completed it a year ago, you used to know where a Cat 4C cabin was without looking, now not so much. As of April 1, 2011 (or is this a joke?) NCL will implement standardized categories across its ships, introducing such rare and exotic new birds as Categories MA-MC (mini-suites), T1 (studio), etc.
Confused? Ships are getting bigger and more complex, the Royal Caribbean Oasis Class ships have over 36 different cabin categories, the Norwegian Epic looks like it will have over 45 categories. Recommendation: stick with an agent unless you want to wind up under the disco or next to the kid's playroom!
