We are in our early 30's and went to Alaska two years ago on a cruise. Yes, a lot of the activities on the ship are geared towards the older crowd, but there are so many activities about Alaska, the culture, etc... We would go again in a heartbeat! Yes, it would be different if Disney were to do it I'm sure, but Alaska was incredible. I stood at the front of the ship the day we were in Glacier Bay and cried because it was so incredibly breathtaking. I just kept thinking that in ten years all of that might no longer be there and let me tell you that that would be an incredible loss. This is something I would want my children to see and experience (hopefully, it will be there when I finally have some).
