Just got back from 12 nights cruise to Argentina, Uruguay and Brazil on Oceania's Regatta. This is our first on Oceania. Our cabin is a C-1 deluxe category. First we we so surprised at how small the bathroom space was and lack of closet space. We were expecting a floor to ceiling window at least but is was just a small window. The beds were comfortable. All soda and water were complimentary. In fairness ,Food and service was great at all dining and restaurants. However noticed that their menus did not changed that much so after the 5 to 6 days we seemed to guess what would be for the menus. Our biggest gripe were the shore excursions offered. Besides being expensive, some of them were not worth the money.
The reason we chose Regatta is because we thought being port intensive we will be seeing great places. Five of the ports were tenders. Montevideo and Punta Del Este (Uruguay) were a little bit more interesting. However all the other ports, Rio Grande, Porto Belo, Parati and Ilha Grande (Brazil) there was not much to see. Oceania should just skip some of these and spend more time on ports that offer more. Buzios, Brazil was more of a shopping port, but not much. One of the worst shore excursion was in Sao Palo, Brazil. it took almost 11 hours with 2 stops (non picturesque) and a lunch.
A lot of passengers were unhappy. Entertainment was so so. Their lounge is small (cabaret style). Not too many activities on board. No movie theater but you can take out DVD and watch it in the room in you care to watch it on a very small screen. If you care for food and service only then choose this cruise. We can not recommend this cruise to friends and relatives. There should be a balance as to overall cruise amenities considering that Oceania is suppose to be upscale than Holland America or Royal Cariibean or Princess cruises.
The bathroom was small compared to other bathrooms we have encountered with other cruise lines.
