While it is fun to discover the ships areas, such as during a scavenger hunt, it is important to note the part at the wiki site that reads "This door may be marked Crew Only, if so please follow the rules and do not enter."
I suppose there is no penalty if a pax is found in these areas?
The new ships tour takes pax to the bridge, galley, and, surprisingly, crew areas. After 9/11 the tour was discontinued but it is returning.
