Sixteen of the rooms will be deluxe verandas and two will be slightly smaller verandas. Four will be standard insides. Passenger capacity will increase to 837 from 793.
The addition of the staterooms aft will expand the pool deck to allow for more deck chairs and the new bar.
Other standard maintenance and technical service will take place along with upgrading of the laundry and galley equipment.
HAL said the new staterooms will be fully finished while the Prinsendam is under way. They will be bookable for the 54-day ‘Quest of the Argonauts’ voyage sailing March 24 round-trip from Fort Lauderdale to the Mediterranean and Black Sea with stops in New York City and Bermuda on the return.
The Prinsendam entered service in 1988 as Royal Viking Sun and later sailed as Seabourn Sun prior to moving to the HAL fleet in 2002.
