Royal Princess to Alaska Seattle round-trip was a great cruise. I went with a friend, her young son and her brother in early August. Embarkation was super easy, and I found the Blue Lane vs Green Lane to be a meaningless distinction, and picked up my medallion at the same desk as registration, and from getting out of the cab around 11am to being on board took less than 20 minutes.
The ship is in excellent shape, and our obstructed balcony cabin was great, on the Emerald deck (deck 8). The lifeboat below us obstructed our view straight down but I didn't find that to be an impediment. I like the Princess room layout better than most ships as the closet nicely separates the entrance from the rest of the room. Balcony is small/narrow but very nice to have. My friend's son and brother booked late and were in an accessible interior cabin that was quite spacious compared to most cabins.
Beautiful cruising by the glaciers.
Did an independent whale watching and visit to Mendenhall Glacier. Both worthwhile.
Did the lumberjack show and walked around town. Cute town, easy to get around, check out Creek Street.
Probably the best port, so much to do from here. The White Pass railroad and Yukon excursion was a lot of fun, and included the summer dog mushing for a small additional fee. Worth it, also enjoyed visiting Carcross, YT.
While only having a few hours here, I enjoyed visiting at night, and did the ship's bus tour into town (a short ride). Was able to walk around downtown and see the famous hotel and outside of Parliament.
