May be a little late now...but for anyone still interested...
We just returned from an OUTSTANDING Mediterranean cruise...the best cruise I've ever been on...
Celebrity Millennium...13 nights...
Venice--Dubrovnik--Corfu--Santorini--Athens--Naples--Rome--Livorno--Nice--Barcelona...
I know they do 12 night variations of this through October 14 this year...
The ship, service and food are outstanding...and the itinerary --3 stops in Greece, 4 ports in Italy and one each in Croatia, France and Spain--is great...
