Last year we sailed on the Ruby Princess from Barcelona to Venice. The 12-day cruise that included ports of Monte Carlo, Florence, Italy, Rome, Naples, Mykonos and Delos, Greece, Istanbul, Kusadasi, Athens and over-nighing Venice. Cost was $4,179 for cruise and round trip airfare from DFW. That was a great cruise, fabulous ports and enjoyed very much. Airline booked through Princess Air. We arrived in Venice about noon and it took an hour to get a ferry into the city. Overnight means you get to stay in Venice during the night, but flights begin as early as 6 a.m. the next day.
