The latest major upgrade was completed in 2016 and the ship now carries more Holland America staples. It's got the line's signature Explorations Cafe by the New York Times, a lovely reading room and library. The Pinnacle Grill, Holland America's alternative restaurant that serves Northwest-inspired cuisine, has a fresh look and new menus. Cabins were refreshed with new carpets. And the ship, which has never been marketed as a family-friendly member of the HAL fleet, now operates the Club HAL kids' program (though there's no dedicated facility and counselors are only onboard during holidays when multi-generational groups are likely to be traveling).

Originally named the Royal Viking Sun when it debuted in 1988, and later the Seabourn Sun, the vessel has always been one where passenger comforts rank high with officers and crew. That philosophy has continued with Holland America. The ship's guest relations desk, for example, is visited daily by passengers who just want to say "hi" to staff rather than to voice a complaint.

"As You Wish" dining was introduced on Prinsendam in May 2008, allowing guests to select either traditional pre-set seating or dining on a flexible schedule from 5:15 until 9 p.m. daily.

Ultimately, one of the most delightful aspects of Prinsendam is that it is utterly unique within the HAL fleet -- despite the many features, facilities and amenities consistent with newer, bigger vessels. It's still by and large a ship for more mature travelers who want classic style cruising and contemporary conveniences.
