We booked our 9-Day Mediterranean Cruise for October 21-30, 2022 starting from Rome to Lisbon in January 2021, bundled with air fare and travel insurance/protection. It was so well worth it and the cruise was indeed wonderful!
Air Transportation: With Carnival’s Fly to Fun, I got to choose the dates and airlines that we want to arrive in Rome, and to fly out of Lisbon. It was very easy and convenient to make the selection-- the date, airline, and even the seats. Likewise, the Carnival airplane rates were much less than what was I was getting from the various airlines and search engines that I went into for price comparison.
There were earlier concerns with the final ticketing, but these were resolved about a month before the cruise date. Over-all, we would get the Fly-to-Fun option next time we book with Carnival.
