Our trip on the NCL Star was the 10th cruise for myself, the 5th for my DH. We are in our late 40's and are fairly easy to entertain.
Tip for flying into Seattle... use the shuttle service at the airport. $14 each. Quick, efficient service to the pier. NCL did have folks there to greet us and even though we hadn't bought transfers from them, they allowed us to drop the baggage there. In hindsight, probably wouldn't do that again as it was late before they got to our room, even though we dropped them off there at about 10:30am!
Embarkation was a breeze. Walked into the pier, followed all of the friendly greeters and we were ready to go within 5 minutes. We then waited about 30 minutes until they boarded us. Drinks were provided for our comfort. On ship before noon.
