Went to the Disney Cruise Line site today. The West Coast (http://disneycruise.disney.go.com/disneycruiseline/ratesanddates/itineraries/itinerariesindex?id=SevenNightWestCoastCruiseItin) route is up! Enjoy :)
You might want to call the reservation number or go through a TA -- the site didn't seem to be able to give out quotes for the 7-day.

I've booked my West Coast Cruise for August. I couldn't get the website to work, but I did finally get through on the phone lines. I can't wait!!!!

We're booked for the 14-day "repositioning" cruise from WDW to LA!

I looked at the trip going back to WDW in August, it wasn't that much more that the 7 day cruise, but I've never been on a cruise ship before and I don't know that I could handle it that long.

Have a great time.
