Regatta is a beautiful ship. We were on a 12 day Italian Interludes out of Rome ending in Venice. We stopped in Monaco, Capri, Sorrento, Sicily, Greece, Dubrovnik, and Venice. We were a group of 8 people flew in from the US 2 days before the cruise. Very easy embarking- we waited maybe 30 minutes and got straight aboard.
The service was excellent. It was nice seeing the same staff members every day. I have previously cruised with RCI, Princess, and Celebrity. Celebrity being my favorite line. Oceania had maybe 700 people, which was great with dining- but nightlife was terrible.
The "night club" was an on air jukebox where you could pick songs you wanted to play. The entertainment was in a small ballroom where chairs are set out for guests to sit. This is not by any means an auditorium. The Entertainment staff was very talented, however, the shows were lacking in appeal as I would see many people leave halfway through them.
