There will be 4 of us traveling. (2 couples). We are in our late 50's early 60's. We will arrive in Italy on a Sunday and will leave the next Sunday for a 7 day cruise, then 1 or 2 more days in Rome before we fly home. We can divide the days between Venice, Florence and Rome as we wish. Right now we have reservations at Marriotts in all cities, until we finalize our flight schedule. Any suggestions would be great.
