I am not sure where your starting point is, but you already know that there is only one road to Alaska! Once you get here there are only a few roads that connect the major cities. If you are looking for something difference and have the 'extra' cash you could take the ferry part of the way. Once here, there are several 'side' trip that can be fun, but having been here several times you already know that also.
For us, when we plan a trip to the 'lower 48' I use Street & Trips. I use this program not so much for the route to the 'lower 48' but more for the places that we want to see there. This program also is a good source to provide me with how much fuel I need to plan to buy.
