Thank you all for the input. Not being that familiar with Seattle all of the comments help. I think I need to call the hotel and find out what my options are on their end. Online it said they had a shuttle to the King Street Station, but that could be a very old post and in these times a lot of the things that used to be are no more. They also may have input into covid testing in the area. My biggest issue may be the luggage. We are light travelers, but when going to colder climates coats and warm clothes take a lot of space, and of course we'll probably pack a picnic - or at least some water and drinks - for the trip which would add to the stuff we need to bring. Would probably throw whatever isn't gone away, but would still have the cooler bag, etc. Just glad that I figured the extra day into the mix.
Is it possible to take the tram back south to the cruise port? What stop would we need and how far would we have to walk? Probably just be easier to taxi or uber - a more relaxing start to the trip.
