We cruised for the first time last year and went with Oceania and chose Oceania again this year as we were so impressed previously. We were on the Marina last year and the Riviera is an identical sister ship so we felt at home (even booking the same stateroom number). Whist we deemed this cruise excellent there were some small negatives when compared to last year: the attention to detail in cleaning the stateroom and replacement of bathroom consumables, the difficulty of some serving staff in the buffet restaurant to understand requests and also greater detail in briefing them on the food they were serving would have helped. The entertainment was better than last year (apart from a rather dire ventriloquist who had used up all his A-level material in his first show and was left with nothing for his second show) with a very talented team of core singers who made the shows and poolside performances wonderful. Food was excellent in all the restaurants; the four speciality restaurants exceptional. However, for probably the first time the Brits outnumbered the Americans by a considerable number and so this exposed some failings in understanding UK preferences: e.g., the night they offered traditional roast beef and Yorkshire pudding there was not a roast potato in sight and they totally ran out of orange marmalade by day 3!Looking forward to our next Oceania cruise.
