Do a search for: anchorage b and b and you'll come up with lots of choices. We're staying at Kingsview B&B. The people at the B&B's can give you lots of suggestions.
Tour-wise, I'd go for the 26 Glacier tour out of Whittier. They'll bus you from Anchorage to Whittier. It sounds like a great tour.
I assume you will have a car??? Consider a day trip and overnight in Talkeetna- 2 hours north of Anchorage. Stop at Eagle River Nature Center and Eklutna on the way. Consider a Denali summit fight via Talkeetna Aero Service- also raft rides here as well. Get visitor guides- Anchorage- www.anchorage.net Mat- Su Valley- www.alaskavisit.com
