The Holland America Line Rotterdam receives generally positive reviews for its beautiful, modern ship, excellent staff, and enjoyable itineraries. Guests praise the cleanliness, friendly service, and variety of dining options, especially in specialty restaurants. However, there are recurring concerns about overcrowding, reduced staff, smaller cabins, and a decline in food and entertainment quality compared to previous years. Some guests also mention issues with extra fees, internet quality, and communication. Excursions and port experiences are mostly positive, though some report cancellations and miscommunication. Overall, the Rotterdam offers a pleasant cruise experience, but some aspects have room for improvement.
