What would you do with three days and four nights in Anchorage next month (March)? We are active and have three kids (11, 14, 17). We are considering a dog sled experience, the 6mile hike to Portage Glacier, a day trip to a National Park, Aurora tour...My preference is to stay in an Airbnb and rent a car for day adventures, but I'm open to ideas. This will be our first trip to Alaska, so we know we'll see just a teeny bit.
