Hi Gary, The Pride (my favorite ship) is going to Miami in April 2009. There is going to be a special one time Panama Canal cruise March 22nd.
You can read more about it here.
I haven't heard any news about the Spirit. It is scheduled to go to Vancouver, May through September and then back to San Diego, after a run from Honolulu to Ensenada. As far as I know.
Cruise Fanatic will be back in a few days, and she may have more information.
