My brother and I got off of the Koningsdam on August 12.
The cruise was great. We were in a Neptune suite and had to wait for CO for maybe 10 minutes one time.
The Lido was ok. I enjoyed the salads. The drink service could be hit and miss. One time. My brother got some brisket, but when he got to the table, he noticed that it was almost all fat.
As far as the the Lido, do not count on getting orange juice with breakfast unless you are willing to get up and ask for it. Likewise ordering soda, etc can be a challenge.
We ate breakfast there one morning, and I was served a scorched omelette.
We have booked a 2 week cruise on the Nieuw Statendam next year and will avoid the Lido when we can.
