Oceania Nautica receives high marks for its attentive service, excellent itineraries, and generally high-quality food, though some guests note a decline in standards compared to previous years. The ship's smaller size and friendly staff are frequently praised, but recurring criticisms include outdated cabins, small bathrooms, inconsistent food quality in specialty restaurants, and disappointing or overpriced excursions. Entertainment and onboard activities are seen as adequate but not exceptional. Internet connectivity and value for money are also common concerns. Overall, Nautica offers a premium experience, but some aspects are in need of modernization and improvement.
