Oceania Regatta receives high praise for its attentive service, excellent food, and intimate ship atmosphere. Many guests highlight the friendly and accommodating crew, comfortable cabins, and well-maintained ship. However, some reviews note inconsistencies in food quality, outdated bathrooms, slow dining service, and issues with excursions and itinerary changes. While the majority of guests feel the cruise offers good value and a luxurious experience, a few express disappointment with missed ports, communication lapses, and the ship's aging facilities. Overall, the Regatta is recommended for those seeking a smaller, more personal cruise experience, though some aspects could be improved.
