587 Oceania Riviera Cruise Reviews. Oceania is totally over rated! Loved the itinerary - many locations we had not visited. However a horrible cruise overall. Booked our flight through Oceania as part of the cruise package and arrived at the airport to find out that our flight was cancelled the day.
