The price went up, then down, then up from what I can see. When I was on the koningsdam in March I paid the $65 or whatever before the discount. I “think” that included the 18%. A couple months back I started a thread saying that the price had gone down the the $47.20 including the service charge. I booked 2 reservations for my next cruise. When I looked at my app the price was up again. I should have booked more with the “sale” 😛.
