The Holland America Line Rotterdam receives generally positive reviews for its beautiful, modern ship, excellent staff, and enjoyable itineraries. Guests praise the ship's cleanliness, comfortable cabins, and good food, especially in specialty restaurants. However, there are recurring concerns about reduced staff, crowded public areas, inconsistent service in dining and bars, and a decline in some traditional amenities. Entertainment is often described as underwhelming, and internet connectivity is a common complaint. Excursions and communication about them can be hit or miss. Overall, the Rotterdam offers a quality cruise experience, but some guests feel standards have slipped compared to previous Holland America cruises.
