I was checking out the Alaska Ferry online, from Whittier to Valdez, and it looks like a doable option for me and my wife in our 24' rental RV, but a little pricey. Does anyone have any experience doing this? We drove from the KP up and around to Valdez last year. It was a beautiful drive, but burned a ton of fuel in the 30' beast we rented last year. On top of that, it consumes the bulk of a precious AK day. Just looking for some thoughts. Thanks.
