Actually nobody disappeared. The Senior Vice President of Marine Operations retired with 8 months notice, and the Senior Vice President for Hotel Operations went back to the parent company with 2 months notice. There was a consolidation of some duties and there is still a position that is currently being recruited for.
Mr Hamlin's experiences and successes in the shipping industry have positioned him perfectly for his new duties at NCL.
It doesn't seem to me that there is any conspiracy or hidden agenda in any of this news. In fact these changes along with the (gasp!) unannounced creation and filling of the position of Chief Information Officer are just changes that every large corporation go through as they adapt to the changing marketplace. No company is compelled to release that kind of information.
Just as a side note I contacted the public relations departments of HAL, RCCL, NCL and Carnival here is what they stated:
HAL - does not release any press releases regarding personnel issues
NCL - Same as HAL
Carnival - Will release information only when there is a formal inquiry
RCCL - Has made 7 "senior level management changes/revisions" in the last 10 months.
Maybe we ought to get Mel Gibson involved...we could make a movie and call it Conspiracy Theory 2 - Munity on the High Seas..............
