I am travelling to Alaska for July 4th weekend. I arrive on the 1st at 6pm in ANC and depart from ANC at 6am on the 4th. I realize that this is not nearly enough time to see Alaska, but I would like your help on picking what the priorities should be.

I am thinking about renting car and driving up to Fairbanks and back (I looked into the train, but it is much more expensive, so I saw no reason for it). Is that a good idea? If so, what side trips should I make?

I don't truly care if I spend a lot of time driving, neither which town(s) I sleep in - I have no hotel reservations at this point.

Thanks!
