The speculation is that if they build a third ship, they would position it on the west coast. The logical thing to do would be to package it with the
Disneyland Resort as they do with Walt Disney World. The port of Los Angeles is only about 30 miles from Anaheim. The port of Long Beach is probably a little closer. They could keep the ship in LA during the winter and move it to Alaska during the summer. Makes perfect sense, now they just need to build a ship.
BUT (there's always a but...) they have not yet ordered a ship and no major shipyard has announced a contract to build a ship for
DCL. So, if they started building the thing today, it probably would not be in service until 2005.
In the meantime, HAL is a good choice for an Alaska cruise. Their ships are every bit as elegant as the DCL ships, although there's a little less energy on board, as they don't cater to the same type of crowd as Disney. Princess, Celebrity,
RCCL and Carnival all have some of their newer ships in Alaska during the summer. RCCL's Radiance is a really nice ship, I've saild on it in the Caribbean, but I believe they re-position it to Alaska in the summer.
