My wife and I recently took the Silver Shadow to Alaska. It was my last chance. After all my complaints about past cruises never matching my experience on the "crossings" I took in the 50's and 60's, my wife told me that this was the final straw. Bottom line: we had a wonderful time, but be prepared for a few surprises and disappointments. And let me offer a few tips for future cruisers.
First, we had a Grand Suite cabin. We always go suites -- not because we're stuffy, but because I get so little free time from my practice that if I'm going to go, I want to go in style. The cabin was fantastic. Your own private apartment. Bedroom completely separate (read: closed door) from the living area, which itself is spacious. Butler and attendant couldn't do enough for us. Mention a preference for something, it appeared each night (mixed nuts, sliced lime for our G&T, sushi/sashimi appetizers, my wife's favorite white wine, etc. etc.). Always low key; always without any sense of effort or duty. They were here to please.
The problem with the GS and RS cabins is that they get too much light. The curtains and shades are wearing thin and several requests to repair these were to no avail. Plus, being on deck 8 and at the bow, you felt every wave hit the hull. Strong recommendation: if you want a larger suite, go for the Silver or Medallions on 7 and stay away from the bow.
Stay away from 802. It is too high up and being at the bow means you get all the sunlight and hear all the waves. You are also right under the bridge, so get all the creaking from the ship's crewing walking about.
