I cruised Koningsdam for 24 days from 10/18/2018 to 11/11/2018. She is about 2 years old and appears to be in very good physical condition and is well maintained. That said, Koningsdam is a mixed bag of good, bad and ugly...in this writer's experienced opinion.
By all appearances, the ship is being kept very clean. Wear and tear has not yet begun to show too much. Not much rust in sight.
The theater (World Stage) is the best in the HAL fleet, and maybe in most fleets. Sight lines are excellent and there is hardly a bad seat in the house. Seating capacity is relatively generous and can fit about a third of the passengers at any one time (close to 800). That said, there were many occasions when the theater was totally filled and people were standing and/or sitting in the aisles (safety hazard?). The hi-tech stage uses a 270 degree computer controlled LCD screen as the backdrop and is the main apparatus of the otherwise sparse set decoration.
Lincoln Center Stage is an outstanding plus for HAL. Koningsdam's venue for the very talented quintet is larger than other ships in the fleet and offers comfortable seating.
Public seating is excellent and comfortable throughout the ship.
The staterooms are a bit smaller on than most of HALs ships, but they are reasonable equipped. Electric and USB plugs are abundant and storage/closet space is good.
While Koningsdam is new and bright, HAL has done nothing to change the nickel-and-dime operation and product they offer. EVERYTHING they do is designed to get passengers to spend more money. Most of the daily on-board programs offered are for revenue and income production.
Venues throughout the ship are too small for the large number of passengers, often filling an hour or more prior to a presentation.
The Culinary Arts Center is the showcase venue for America's Test Kitchen, and it is very ill-suited for the purpose...very poor seating and sight angles. They also utilize this room for extra-cost dinning in the evening (much more suitable).
The Mariners Program on Koningsdam appears to be treated more as necessary nuisance than as the customer building program it was originally designed to be. There does not appear to be a suitable venue on Koningsdam for a Mariners Reception, so only medallion recipients are invited, no matter how many medallions one has or how many cruise days you've logged. The multi-Star Mariners cocktail party is held in part of the Lido Pool area, while other people are in hot tubs on the other side. It's very clear that HAL management wants to change the demographic of its customers. They are looking for new, free spending blood.
Staterooms are noisier than one would expect for a "new" ship. Even in slight seas there is creaking, rattling and banging...especially at night when you are trying to sleep.
Fit and finish is not all that it could be. As an example, stateroom have a recessed "frame" for the wall mounted large screen TV. In my stateroom the TV was mounted well out of the center of the frame and lop-sided (one side higher than the other).
The Main Dining Room is very noisy, especially on the lower deck (Deck2). There is little or no sound-absorbing material to soak up noise.
There is no replay of the excursion or enrichment talks available on Koningsdam's closed circuit TV system or on stateroom TVs. You can, however, book extra cost dining, spa and excursion options via the interactive TV system.
What little "art" there is on the ship is far removed from traditional seafaring art. All is very contemporary and the artwork appears to be photo-shopped pictures. There is NO art in stateroom passageways.
Passage fore and aft on public decks 2 and 3 is restricted to one side of the ship, ensuring exposure to every selling station onboard.
Traffic flow is poor, especially outside elevator locations where they have planted large modern sculptures (?), creating bottlenecks.
The Promenade Deck is quite narrow and there are no deck chairs thereupon. The walking gets very bottlenecked at the stern end of the ship, so if one is walking behind slow walkers or encountering walkers who insist on walking upstream, it slows everyone down. Not important enough to write Congress about...just a mention.
Whoever designed the toilets in the staterooms should be fired immediately. One cannot sit "on the throne" straightaway. You have to sit sideways because the glass shower enclosure is in the way, and you can't get your knees to squeeze in...unless you're 2 or 3 years old. Very awkward and uncomfortable.
This is a very subjective area and not all tastes are alike. So offering comments about the food and service aboard the Koningsdam is treading on very dangerous ground. That said, HAL has put together a fine group of chefs in what they call the Chef's Counsel, to help Chef Rudy design a dining program for the ship's various venues. They have created offerings that, in their test kitchen, appeal to all the senses. Great food requires great ingredients skillfully assembled by craftsmen who love their work. Unfortunately, the Chef's Counsel is not on board to supervise the final product. HALs logistics program is complex and mainly designed to minimize costs and maximize efficiencies. They do not take advantage of the terrific local products as they cruise from place to place. So freshness of ingredients is sacrificed in favor of program convenience. They claim there are reasons (or excuses) for this, but others seem to be able to take advantage of local fresh product availability. That's all I have to say about this topic. Everyone has to judge for themselves.
