We are traveling on a last minute cruise to Alaska on Nieuw Amsterdam, so the stops are Juneau, Skagway, Ketchikan. We have a two year old and need suggestion on excursions. I want things to be safe and because the weather is expected to be in 50s, nothing which exposes us to too much wind. Only thing I have come across is the White pass train. So, any suggestions on what to do is welcome. Also, should I buy the tickets for the train on my cruise?
