BirdTravels, thank you for the picture of the dock in Juneau, that helps with the distance.
I have another question, it appears there is no requirement to take a COVID test prior to disembarking in Seattle, correct? When I booked last year they said everyone would be given a test onboard prior to arrival back in Seattle (did this on our transatlantic last November when we came in to FL). But looking at the departure letter you posted and the RCCL Checklist email I got today for our cruise in a week, it doesn't appear as though that is still required. The Checklist says each guest should check their home country's testing requirements and plan to travel with a test kit to meet re-entry testing requirements if necessary for their home country. Based on all of that, I'm going with we don't have to test prior to returning home to Ohio. Thanks again for all your help!
