Hi smart424. All I've been able to find is that she will be in wet dock in Honolulu for six days in February 2008. They'll be adding a casino as well as NCL's infamous "hull art," which is why it's able to be done so quickly. I'll keep searching for the name of the dockyard.
Looking at the Pride of Hawaii's remaining schedule, and the Norwegian Jade future schedule, there isn't much time for a wet dock in Honolulu. Pride of Hawaii 7-Day Hawaii, Round-trip Honolulu 2007: November 5, 12, 19, 26; December 3, 10, 17, 24, 31; 2008: January 7, 14, 21. 12-Day Hawaiian Escape, Honolulu to Los Angeles 2008: January 28. Note: There is a 6-7 day gap in Los Angeles. Norwegian Jade 13-Day Panama Canal, Los Angeles to Miami 2008: February 16 Note: There is no time gap while in Miami. 13-Day Transatlantic, Miami to Barcelona 2008: February 29 Note:: There is an 18 day gap while in Barcelona. 12-Day Classic Mediterranean, Barcelona to Istanbul 2008: March 30.
Therefore, the wet/dry docks probably occur in California and Spain. No ship is left idle, out of service, intentionally for 6 to 18 days unless the ship is in a shipyard for refurbishment and maintenance. I expect a wet dock in California for the crew changeover and inspections for changing the flag. I expect more maintenance and refurbishments will be performed once it arrives in Europe. I'm not sure 6-7 days is long enough to remove cabins on Deck 6 to install a casino while the ship is in California. But if it is, there will not be much time to do much more.
I don't know which shipyards are scheduled to do the work.
NCL obviously added the 12-nighter to LA after posting this press release on its site, which hit many news outlets. Too bad they did not give the same attention to publicizing the PoH farewell cruise.
I still don't know the name of the shipyard, smart424. I need to call my contact at NCL this week regarding something else--employees tend to know a lot more than the general public, so I might very well get an answer.
