It's not just the inside passage where wifi gets wonky or non-existent. It can be anywhere in the state. Near the cities it should be fine. I use a VPN when I am not at home and it does slow things down. Sitka and Juneau are great and there should not be a problem unless there is a pesky mountain in the way. Usually someone on the crew will be able to say, "As soon as we get around that peak".....I doubt that it would be a whole day but it does depend where you are.
