G'day jkshu, and welcome to cruise @ddicts.
DH and I sailed with a group on Sea Princess to Alaska, 10 nights, from San Francisco in August last year and we had a great time. We stopped at Ketchikan, Juneau, Skagway, and Victoria Canada.
DH and I only took one ship's tour; Skagway, White Pass train. We thought that was well worth doing. The other Alaska ports we just wandered around and looked at everything. Being Aussies, this was a great experience for us.
We had a cabin on the same deck as the casino, deck 8 I think. (brain gets a bit scrambled after long haul flights) The room was fine, cabin steward was great. I have a review here on @ddicts. I, and a few of the group also have photo galleries here of this cruise.
I know this isn't much info, but I hope it helps.
Cheers.
