The Holland America Line Rotterdam receives generally positive reviews for its beautiful, modern ship, excellent staff, and enjoyable itineraries. Guests praise the cleanliness, comfort, and service, but note some declines in food quality, entertainment variety, and staff-to-guest ratios, especially when the ship is at higher capacity. Some guests mention issues with crowded public spaces, smaller cabins, and extra charges for amenities. Excursions and communication can be inconsistent, and the internet is often criticized. Overall, the Rotterdam offers a pleasant cruise experience, especially for those seeking relaxation and attentive service, but may fall short for those expecting top-tier entertainment or more spacious accommodations.
