Harmony of the Seas receives high praise for its impressive ship design, friendly and attentive staff, and a wide range of activities and entertainment options. Most guests found the ship clean and well-maintained, with excellent service and enjoyable shows. However, some guests noted issues with crowded areas, elevator wait times, and mixed experiences with food quality and specialty dining. Pricing for extras and specialty services was also a point of contention for some. Overall, the cruise is highly recommended for families and those seeking a lively, activity-filled vacation, though guests looking for a quieter or more intimate experience may find the ship overwhelming.
