Good luck on the Koningsdam, it is a beautiful ship. Strongly suggest using the Verifly App for boarding. When we went for embarkation the room was a mass of people with huge lineups, except the Verifly line. When we said we had Verifly we were walked right up to an agent, no waiting. Suggest bring your own supply of masks, ones from HAL -one broke immediately and they ran out of replacements. I had my own supply with me.
