we flew into anchorage and rented a motorhome, unlimited miles. we put almost 1900 miles on in 2 weeks.
cheaper than a car rental+ motels + restaurants.
we went in late july/ early august, weather was nice, comfortable.
go south out of anchorage towards seward, plan on 2-3 days in this section. take the cruise out of seward you will see wildlife up close, well worth the money, also get the buffet, best deal we found for food.
then head up to Denali, wonderful place, give yourself time.
if time still permits head to fairbanks then run down the richardson highway, to Valdez. crown jewel of alaska.
then run the only road back to anchorage.
just a side note, a subway 6 inch sub meal was only $11.
1 day car rental was $145
motels, when you can find them run between 100-200 a night.
note motorhome rent out quickly, we reserved in january for a july vaction and almost didn't get what we wanted.
don't delay too much if you really want to go.
pm if you want more info.
