I pretty much have my itinerary firm now that I could book flights with DL/AS using miles for the trip between MSP and ANC/ADQ. Traveling in early July.

MSP to ANC, two nights
ANC to STG, four nights (at the only hotel with kitchen, no restaurant)
STG to ANC to ADQ, one night
Seven nights in a Forest Service cabin in the Kodiak National Wildlife Refuge (bear viewing and photography)
ADQ to ANC to SEA to MSP all in one day (including a redeye SEA-MSP)

All that for 25K DL miles, $10 in security fees and a free PenAir ticket for being bumped. The MSP-ANC-ADQ round trip would otherwise cost $886. ANC-STG round trip would cost $962. I would never pay either of those fares, so I can't say my miles are "worth" that, but still a good return on miles.
