My wife and I are experiences cruisers with thirteen ocean cruises and two river cruises in the past. We have sailed with RC, Celebrity, Norwegian, Carnival, and Princess previously.
Our only previous experience with Princess was the Golden Princess in 2001 shortly after it entered service.
We picked this cruise because of its wonderful itinery - Venice, Dubrovnik, Corfu, Sea day, Instanbul, Mykanos, Athens, Santorini, Rhodes, Kusadisi, Crete, Sea, Naples and finishing at Rome.
Good cabin, lots of closet space, seems bigger than RC cabins.
