We sailed in early August on the Joy out of Seattle. This was our 4th family trip on a cruise and second on NCL.
We spent 2 days in Seattle prior to boarding the Joy. We had great weather and our hotel downtown (Hilton Garden Inn) was nice, clean and convenient. My parents were staying at the Westin, also downtown, and they enjoyed it as well. We did the usual touristy things in Seattle and enjoyed the nice cool weather. Since my parents were there a day longer than us, they did a wine and chocolate tour which they really enjoyed. We all did a Seattle highlight tour and of course the Space Needle. My husband and son took an uber out to the Boeing plant for that tour and enjoyed it. In addition, we went to Pike's Market and had a great lunch on the water.
We booked this trip sort of last minute, (early June) but we were lucky to get great cabins located fairly close together. We had our 12 year old son with us along with my parents and in-laws. We all had mid-ship mini suites with balconies. The cabin didn't seem to be any larger than cabins we had before on NCL, but the bathroom was much larger. The shower was very nice and there was a double vanity and lots of storage. I also thought the closet was well organized and there were multiple cabinets in the cabin. Plenty of room for us to unpack. On previous cruises our son stayed in another cabin with our older daughter but since she couldn't go on this trip he stayed with us in our cabin. He said the sofa/pull out bed was comfortable enough. The cabin was a little tight when the bed was pulled out but we made it work.
