Possessing one of the highest ratios of space per person in the Holland America fleet, the 1,848-passenger Oosterdam boasts innovative, luxurious features. Expanded spa facilities -- with 11 therapy rooms, hydrotherapy pool, sauna, steam and aromatherapy rooms -- pamper passengers in one of the cruise line's most spacious spas. Elevators -- two are glass-enclosed with panoramic ocean views -- give access to 11 passenger decks, including a covered promenade that encircles the entire vessel and two interior promenade decks. Each stateroom is fitted with a data port for Web access, and there also is an Internet center and library. When it comes to dining, the Oosterdam offers a variety of options: gourmet meals in the two-tiered main dining room, a fine Italian restaurant, a casual eatery, a grill and a cafe that serves late-night snacks. Room service also is available at no additional cost. Activities on board include shopping in the duty-free shops, gaming in the casino, trying out the golf simulator or playing on the sports deck. Entertainment is equally varied with nine different nightclubs and lounges, including the thrilling views from the Crow's Nest. Club HAL provides younger passengers (ages 5-17) with supervised programs in the Kidzone and Waverunner rooms.
