We've booked some great excursions, but are not sure what to do with the Talkeetna/McKinley Princess portion. We are scenery junkies and taking the the Tundra Wilderness Tour in Denali, a float trip in Kenai, a 9 hour Skagway to Carcross train trip, whale watching in Juneau with Orca, a float plane trip in Ketchikan with Island Wings, etc. What would you suggest for two 60-somethings who are a lttle past heavy hiking. Since we're taking a float plane in Ketchikan, is it worth spending more big $ for a plane in Talkeetna? Do you have other suggestions? Thanks so much!!
