We just got off an RT Vancouver Alaska trip on Koningsdam May 14. They did not advertise it, but all you had to do was go to the customer desk and register for the Friday COVID testing. You received a time, and ship medical staff tested everyone that signed up. Approximately 30 minutes later if you did not receive a phone call in your room, you were negative. Your results were then delivered to your room that evening. According to the Medical staff, nobody tested positive from those of us that signed up. The testing was free. I do not know if there was testing at the shoreside or not. Per the Captain, ship staff were tested twice daily.
