Oasis of the Seas receives high praise for its impressive ship design, variety of activities, and attentive service. Many guests highlight the ship's cleanliness, entertainment options, and family-friendly atmosphere. However, some reviews note issues with overcrowding, long lines, and declining food quality in main dining venues. Specialty restaurants and staff service are often commended, but there are concerns about cost-cutting, extra charges, and the need for better organization during peak times. Overall, the cruise is recommended for families and those seeking a lively, activity-filled vacation, though some experienced cruisers prefer smaller ships or more exclusive experiences.
