That will be awesome, enjoy the sights! It's amazing how far away everything is in Alaska once you get out of Anchorage proper, "Hey we're going to go to the next town over" is an all-day affair haha.....
I love the small touristy town of Talkeetna and the views of Denali from there along the Sustina River, just breathtaking. Yes places like Seward are truly one of a kind! I loved the village of Whitter, you have to drive through an old one lane train tunnel carved out of rock (traffic is stopped for hours on each side of the tunnel and has set times of day you can go through) and when you come out on the other side you are greeted by this tiny boating town nestled along Caribbean-like blue waters with glaciers surrounding you, in the middle of summer, surreal.
