My husband & I (both in our 40s) went on the Legend Northbound May 31, 2002 and loved everything about the ship. If you have any questions, just ask. We didn't take a cruise tour although many people on this cruise did. NEXT time we go to Alaska we will!
We also stopped for a short time at the Raptor Center on our excursion in Sitka and we enjoyed it. It was interesting but isn't necessary to spend a long time there.
