I originally planned to do the Mendenhall Glacier Native Canoe Adventure and a whale watching excursion in Juneau. I am now thinking of doing the Taku Lodge Feast w/ 5 glacier seaplane discovery. If I add that one, I have to not do either the whale watching or the canoe trip. In Skagway there is the Glacier point Wilderness Safari that I can take in place of the Juneau canoe trip. Is one better than the other?
