Just to throw a wacky idea out there.
As the new ship comes online to run the 7-night Caribbean cruises, the Magic departs for California going EASTBOUND.
5-7 night cruise - Depart PC for the last time to
Castaway Cay, then up to Bermuda and into New York. Do "Good Morning America" from the dock as the ship comes in to dock.
If necessary, run down to Norfolk, VA for drydock to outfit for West Coast operations. Shakedown on the way back to New York.
10-night Atlantic Crossing cruise. Run this one for elegance (Princess Aurora's Ball, Cinderella's Ball, etc.) like the old Atlantic Steamships.
10-11 night Med Cruises. Limited number to keep interest high (hint, hint there is a new ship coming online in 2011/2 - wink, wink, nudge, nudge).
14-night Suez Canal passage to Dubai, UAE, then to Mumbai, India, Colombo, Sri Lanka, and Singapore, Malaysia.
14-night Western Pacific Singapore to Hong Kong (Tie-in with Hong Kong
Disneyland), Taipei, Taiwan, and Tokyo, Japan (Tie-in with Tokyo Disneyland).
10-night Pacific Crossing to Hawaii (Tie-in to new Disney resort). Several island stops on the way in.
10-night Pacific Crossing to new home. Several island stops on the way out, stop at Ensenada (for legal reasons).
Anyone with enough money can book the back-to-backs for an "around the world" cruise.
