Luggage question for Seattle to Vancouver transfer

[Cafabi]

We are taking a motorcoach through Princess/Worldwide Shore Services from Sea-Tac to Vancouver to board the ship. Will we have to take our luggage from the bus to the ship, or do they do it for us? Thanks.

If you've tagged it, they'll usually offload it and give it right to the stevedores when you pull up to the ship. They do that with the YVR transfers at least - you don't have to claim your luggage at all. They just take it right from the bus. I would think it would be the same for your bus trip too since it's basically a really long "transfer" of sorts.
