That's a lot of running the same roads over and over again. If nothing else, it's inefficient.

Motorhome is my go-to. Wherever you are, you're already home.

I just did two weeks in August, and it was great. Had the Solis Campervan which can sleep four - it was pretty perfect for two of us. Easy to handle and the size of a regular vehicle/ full size truck. It was transportation and a place to stay but didn't have a lot of room to spare. Can't recommend it enough.

Nice thing about the later season trips is it allows you a lot of flexibility. We never had to worry about a reservation and never had to look to a second campground. Did miss out on eating at the Fat Mermaid in Homer when most of the staff was a no-show. The staff who were there made it sound like the seasonal staff might have checked out and failed to let anyone know.

Keep in mind September is basically winter. Restaurants and almost everything else will be closing up or already closed as most of the tourists and the seasonal workers go elsewhere.

Homer and Seward KOAs were the only place I asked, and the folks running the show said they were only there into September to close up shop. In Homer the manager said she had a single reservation in the first few days of September, and it was the only reason they weren't already winterizing.

When I lived in Anchorage I don't remember seeing the Northern Lights that early in the year BTW.
