We just returned from a 7 night cruise to Alaska from Seattle, WA. Since we live in WA, it was nice to not have to worry about plane fare. We had Shuttle Express pick our party up from our house and drive us right to the Pier. We have never had such easy boarding before. You wheeled your luggage in, then went to the counter to turn in your cruise documents. What was nice was they had Mickey and Minnie come out for pictures, so this took up the time that you had before boarding.
Once you get on, they immediately direct you to the buffet in Parrot Cay or Beach Blanket. Parrot Cay is much nicer and is one of the restaurants you eat in during the cruise.
Our check in card said that rooms wouldn't be ready until after 2:00 p.m. This was correct. We went up earlier only to find a red strap across the cabin corridors saying that rooms weren't ready. Have your swimsuit handy so you can swim if you are waiting to get to your room.
