One cruise with Oceania was enough to convince us to never consider sailing with any other line - and we have tried many. The Riviera is simply stunning, with a museum's worth of artwork. The staff are consistently delightful, the food always superb and the cabins lovely, particularly the sumptous bathrooms (not so much on the R Class ships - the tiny bathrooms in particular leave a lot to be desired). The enrichment lectures are also fabulous. We love what for us is the perfect balance between a la carte (we despise paying for sodas, specialty coffees, specialty dining, etc) and all-inclusive (my Dad is a nonagenarian, so included shore excursions are of no value to us). Dad is treated like family and it never fails to boggle my mind that crew members consistently remember not only our names but also our dining and wine preferences each time we embark on a new cruise. This is not a line for everyone (no activities for kids, limited entertainment, not much in the way of "spills and thrills" activities) but based on the inordinate number of repeat customers we meet every time, it's ideal for a certain niche.
