I thought long and hard about flying up and renting an RV. Finally decided I wanted someone else to worry about where I'd spend the night and where I'd eat. I took a tour/cruise option - fly into Anchorage, train up to Denali, bus to Seward, boat to Vancouver. Water, trees, a few animals. There's really not much to see without taking the local tours that are easy to arrange on a cruise. Worth the trip and now I'm satisfied I know what Alaska is like. For the future, there's just as good scenery and animals in the Rockies and much closer.
