We are on the June 22nd Constellation out of Ravenna. We are flying into Marco Polo and wanted to stop in Venice for lunch so I called Celebrity to see when the latest we could check in. I was told that 3:30 is the latest, if we are delayed then we need to call them. (thats 20+ minutes on hold). So we are going to drive the 2 hours to Ravenna, check in then either head 2 hours back or go to Venice early on Friday.
