We just returned from a 10 day cruise on the NCL Breakaway. We used Shared Shuttle to go from FCO to our hotel and also from our hotel to the cruise port. Our flight home was canceled, so we had to stay 2 more days in Rome. I emailed Shared Shuttle and asked if they could take us to a hotel instead of the airport when we disembark. I also asked if they could take us to the airport from the hotel 2 days later. They agreed and gave me pricing (almost 100 euros more than our original quotes!). I replied and requested to pay our original quotes.
They replied "don't worry you have same prices." Our pick-up from the cruise port was great, but 2 days later, no one showed up to take us to the airport. I called and they said there was no reservation made. I sent the email to show the reservation, but they said there were no drivers available. We took a taxi instead. What a stressful situation!
