The 5 of us shared 2 cabins. My mother(75), Daughter(17) and Son(19)shared one cabin and my wife and I the other.
First I would have to say I am glad they are moving the cruise to Seattle next year. Flights to Vancouver were at least $200 more per person than similar flights to Seattle. Customs was a hassle at the airport and getting on and off the ship. Vancouver was nice, but not worth the extra hassle and expense.
The service was great. I can't believe how many couples take 2-4 year-olds on a cruise to Alaska. Entertainment was good. The patches worked great for my wife and son. My son appreciated the quality of the 3rd bed in his cabin (much better than a typical sofa bed).
