Thinking way ahead, my wife and I are thinking of going to Alaska for a week in May. We'd arrive on a Saturday afternoon and depart the following Sunday morning. I'm thinking of flying to ANC and visiting Denali for two days and Seward and Kenai Fjords for a day. Is this doable, or too ambitious?

Also, does the bus trip into Denali happen during May? We're thinking of the 13th to 21st or the 20th to 28th.

Any other must-sees on a 7 day trip centering around ANC?

Alternatively, what would your ultimate 7 day itinerary be in Alaska, flying into ANC, FAI, KTN, or JNU? I'm having a hard time deciding if ANC is even the best place to start/end the trip.

[edited to add: I am aware that Alaska is far too big to see in a week. I just want to figure out the best slice to sample for a week. I plan on returning eventually. ]
