We traveled on the Norwegian Pearl to Alaska on August 11th through 17th and in general had a good time with a few bumps in the road. We were a group of three adults, two of us first time cruisers.
Embarkation:
Our flight into Seattle got in very early on the morning of the cruise so we took our time getting down to the cruise terminal. A good tip if you are flying into Seattle: Use the Link Light Rail to get to Downtown (http://www.soundtransit.org/rider-guide/link-light-rail). It's only $2.75 for adults and will take you all the way to Westlake Center. It takes about 35 - 40 minutes because of station stops, but you get to see a bit of the Seattle area on the way. Much cheaper than a taxi and it's a leisurely walk to Pier 66. We did the walk to the pier with one large bag each and a small carry on. Again our group was three adults, this might not be a good option for you if you are a large group or traveling with small children and luggage though.
Our room was a good size for three people - I wouldn't want to be in there with four though unless you plan to spend a lot of time outside of the room. You do a lot of dancing around each other to move around. There are lots of drawers and a full closet for your clothes. The balcony was large enough to sit and stretch your legs completely out which was nice. The bathroom was a good size with separate areas for toilet and tub/shower. This room has a balcony neighbor on the left side but none on the right and was near the elevators - but not close enough to constantly hear people. It was also very near the room where you can view the ship's control room - we visited often because of that.
