Greek cruise out of Venice, any help would be great

We a doing A 9 day out of Rome on Royal Caribbean in June. Sicily, Athens, Santorini, Mykonos, somewhere in Turkey and Naples IIrc. To be honest we chose that strictly because it fits the dates we needed. I have taken a 7 day Norwegian western med out of Barcelona that was great too.

Have you ever been to Venice? If not, why not?

I'm not sure it would be my first choice of cities to go out of, but I've never done a cruise from there so its impossible to say.

Venice is great, but its extremely expensive especially hotels. But the airport is right there, I'd assume other then Rome and Athens its one of the only Mediterranean ports you can fly into directly from the states?
