We cruised on the Oceania Riviera from Athens to Monte Carlo. While my husband and I enjoyed the excellent service and the ports, and overall had a great time on the cruise, we were disappointed in the ship.
Unlike the Disney and Celebrity ships, the public rooms had no "wow" factor, and the decor was not impressive. The bright lighting, sheer curtains, and Muzak in the dining areas detracted from the experience. There was no decent live music, and no entertainment to speak of (this is not a priority for us, but the lack of options was surprising).
The highly touted food was fine, but the specialty restaurants were not appreciably better than those on Celebrity, and not as good as Palo or Remy on Disney. It is a vast overstatement to say that this is the cruise line for foodies. The decor, food and passengers lacked sophistication, and I would not consider Oceania to be a luxury cruise line.
Our penthouse was comfortable, with a great walk in closet. The bathtub was a nice touch.
We stayed at the Hotel Grand Bretagne for one night before the cruise. This hotel was a highlight of our trip. We dined on the roof watching the sun set over the Parthenon.
We enjoyed visiting Santorini, a beautiful island with classic Greek architecture. We had lunch in a little cafe looking over the Mediterranean. The donkeys detracted from the experience of walking down 600 steps to reach the port.
