Holland America Line

Holland America Line's midsize ships, which carry between 1,432 and 2,668 passengers, cater to affluent adults. Each ship provides excellent service, with two or three crewmembers assigned to each passenger.

On Holland America cruises, which leave from cities such as Boston, Fort Lauderdale, Florida, and San Diego and can last anywhere from one to 74 days, you can pass the time with enrichment programs such as digital photography, cooking demonstrations, and mixology workshops, or work up a sweat in spin or Pilates classes before unwinding at the spa.

Though they vary by itinerary, the shore excursions offered by Holland America Line are primarily geared toward adults, with activities ranging from animal encounters to bike tours and even helmet diving. Meanwhile, the dining style of Holland America Line allows for mealtime flexibility. You can socialize with other passengers over a five-course dinner in the main Dining Room, sample fresh seafood in the Pinnacle Grill, or order room service 24 hours a day, seven days a week.
