Boy, I'll say there's a lot to see. My daughter and I are taking an Alaska cruise this summer, number 8 actually. We still haven't seen everything on the inside passage. We have at least two more trips, one on Princess so we can do a pre or post cruise trip into Wrangell-St. Elias National Park to stay in the new Princess Lodge on the Copper River (world's best salmon comes from there) and an expedition sailing up the inside passage. Never had a bad excursion in Alaska.
