My husband and I are very excited to visit Alaska in September! We are planning on taking the ferry over from Valdez with our rental car, spending a few days in Whittier, and then traveling on to Seward and Homer (2 nights each). We are wondering how far the drive would be from Whittier to Seward and then Seward to Homer? What are the roads like to Seward and Homer? Also, is it worth is to bring the rental car on the ferry or would we be able to rent a car in Whittier and return it in Homer then fly back to Anchorage? Any comments are appreciated!
