I used to live in the Yukon and made some trips to Alaska, here's what I know->
Lot's of cabin's around Homer, Alaska, it's a cool little fishing village out on a spit. I personally liked the scenery around Valdez, Alaska the most. And Mt McKinley is a pretty cool mountain. But overall, I would go with Homer, it probably offers all that you're looking for.
It'll still be pretty cold there right now, so bring a coat, and some cabins may be closed for the season. Other than that, the only other thing may be price, most things up north ain't too cheap.
