Alaska is beautiful place to visit. I live in the Yukon, :) its right beside Alaska. We do trips all the time into Alaska. Likes Haines for halibut and crab fishing. Theres a small city called Skagway that has a ferry that goes into Juneau and you can see Orcas and other marine creatures.
There's also a drive you can do that starts in Dawson City, Yukon and it's called top of the world highway. And you go through some amazing places and end up in Chicken Alaska, Tok Alaska and you can head up to Fairbanks.
Its a lot of fun ! Hopefully you guys go and enjoy it :)
