We have just returned from a beautiful Alaskan cruise. This was the 3rd Alaskan cruise for DH, DD, and myself. DD's friend had never cruised before. We drove to Seattle and did the long term parking. Paid online and saved a couple of $$. Very easy and great shuttle driver. We were at the terminal before 11am. Walked in and were greeted warmly and directed to Platinum check in. We were on the ship in about 10 minutes. Quickest embarkation ever.
Headed to the Windjammer for a quick lunch, not very busy and ok food. It got better by day 2. We checked out our table and verified our dining time in MDR, then booked dinner at Chops for day 6pm. (surf and turf available only that day, but you will miss lobster in the MDR)
Sat by the pool and enjoyed the sunshine (bring a change of clothes in your carry on. Rooms were ready by 1pm. No announcement, just told when we came on that they would be ready then.
