We are set to go on an Alaska Land/Cruise Tour which starts Saturday June 4 2022. We have asked these questions several times and keep getting different answers every time. We are flying into Fairbanks 2 day ahead of the Land Tour . We are US Citizens and traveling via Land to Sea through US cities. My first question is Do we need a covid test prior to joining the Land Tour portion of the trip? The next question is do we need a Covid test prior to boarding the Ship and who is responsible to provide this test. The last question is do we need any kind of testing before leaving the ship (Docks in Vancouver) or to travel back to the US?
