For those who want to stay informed...do a little easy research. You can see detailed reports of the most recent (or multiple) inspection of any cruise ship - just do a search for "CDC Cruise Ship Inspections". The CDC site is the official reporting site.
You can see easy to understand information related to any noncompliance and the resulting "fix/corrective action" by the cruiseline in these inspection reports. This may be helpful to you when choosing your cruiseline/ship...or if like me...seeing the problem areas on the ship you're already booked on.
