To add, the Sun will still do Alaska cruises during the summer 2007 season from Vancouver. After completing the Alaska cruise season it will reposition to Hawaii, taking over the 10 and 11 day cruises to Fanning Island.
The Spirit will reposition from New York City to New Orleans to take over the Sun's Western Caribbean cruises from the Big Easy.
Meanwhile, almost at the exact same time, Fall 2007, the Gem will enter service from New York City doing 7 day Caribbean cruises and four 10-11 day Southern Caribbean cruises. When the Gem starts service from New York City, the Dawn will reposition to Miami and do 7 day Eastern Carribean cruises.
The Pearl will also reposition from Seattle to Miami and do alternating 9 day Southern Caribbean cruises and 5 day Western Caribbean cruises.
Also, the Jewel repositions to Miami from Barcelona with a trans Atlantic cruise, but it may stay in Miami or may repostion elsewhere, it's schedule isn't posted yet.
The last change I'm aware of is that the Dream will reposition to Santiago and Buenes Aires that same fall season from Dover. What ship, if any, that will replace it in Houston is unknown at this time. It could be the Jewel. The last cruise posted for the Jewel so far is the trans Atlantic from Barcelona to Miami.
The Wind is scheduled to leave the NCL fleet in April 2007 and the Crown in November 2007. The Pearl is scheduled to enter service in December 2006 and the Gem is tentatively scheduled to enter service in November 2007.
