Carnival one-day sale today on a year's worth of cruises

Carnival Cruise Lines has a one-day sale today offering savings and free upgrades on almost all its cruises -- ranging from three to 12 days -- between now and August 31, 2009.

You could start with a $199 per person rate on an inside cabin on a four-day Western Caribbean cruise departing Miami September 8, 2008, aboard the Carnival Fascination. That's $50 a day for a voyage to Key West, Cozumel, and back. Or you could pay a bit more ($249) for a similar cruise aboard the Imagination on December 15, 2008.

Or, how about a 12-day Northern Europe/Baltic cruise aboard the Liberty out of London with stops in Copenhagen, Berlin, Helsinki, Talinn, St. Petersburg, and Amsterdam on June 2 or 14, 2009, for prices starting at $1,549 per person?

Free upgrades are available within like categories and not all categories are available for upgrade.

More fine print: Government taxes, fees, and a $9 per day fuel surcharge per passenger are additional. The offers expire midnight tonight (August 28, 2008) and are for new bookings only.

To book, call Carnival at 888/CARNIVAL, call a travel agent, or go to the Carnival website here. Be sure to ask for fare code P1S.
