Oosterdam is the first Vista-class ship in the Holland America Line fleet, launched in 2003 and carrying approximately 1,964 guests. She introduced the panoramic Vista Lounge observation area — the predecessor to the iconic Crow's Nest lounge found on later Holland America vessels — alongside the Pinnacle Grill specialty restaurant, multiple pools, a casino, the Greenhouse Spa, and a comprehensive entertainment program. Oosterdam sails Caribbean, Panama Canal, and Alaska itineraries, offering the premium Holland America experience aboard a well-maintained mid-size vessel.
