The Pan Pacific is as easy as it gets! It is connected to the cruise terminal, and you can take a hotel elevator down to the terminal area. When we did the Alaska cruise in 2014, we were able to leave our luggage in our hotel room with the
DCL tags, and it magically showed up in our stateroom on the ship! We even got to see the Wonder coming into port the morning of our cruise. It was a such a treat for us and our daughters.
It is also a lovely hotel with one of the best hotel breakfasts I've ever had (and I've had a lot!). I highly recommend it.
