This is my first cruise. My wife really deserved it. Although I had been in Northern Alaska in the 70's my wife had never been. She wanted to see Brown bears. We live in Denver so we're use to snow capped mountain Bald eagles and other critters plus gold mines and prospectors.
Things I liked:
1: Sitting on a couch in the Spinnaker Lounge drinking a beer and starring out the main window as we left Seattle.
Avoid FWD Deck 4. Cabin 4500. I had originally booked a Window Cabin on deck 8 with obstructed view. My Internet consultant talked me into a porthole window. Beware, that these forward cabins are located over engines the are used to steer into the dock and to leave the dock. If you are sleeping or sitting in your cabin at these times a noise similar to that experienced when standing directly next to a jet engine will engulf you.
There are no coffee makers in the rooms on deck 4. Ask your steward to supply one and it will appear.
Close you porthole at night otherwise if you dock at night you may have a forklift operator on the dock at the same eye-level as you. Put some clothes on!
During rough seas the water pounds against the side increasing the noise level inside the room. Its like sleeping in a car wash with three people trying to tip over your car.
Get a room mid ship or aft. Less rockin.
