Is a National Parks Pass a good idea for Alaska?

[mpk]

For previous Alaska cruisers, are there a lot of National Park type places that charge entrance fees? Besides Denali NP ($10), the others seem to be free. It looks like a Pass just for Alaska isn't needed, unless of course you visit other NPs on other trips.

Probably not needed, there are variety of public "parks" that charge no admission and the Alaska State Parks are low fees too.
