I love Alaska and go every two years. I do have a daughter who lives there so that is a plus. We do something different each time we go and this year we did the Inside Passage which was just beautiful. If you like unspoilt nature then you will like Alaska. I would recommend the day trip into Denalli National Park, saw all wildlife and was blown away by it. Next time we are going to hire a motor home and do a trip further up North we would like to go to Fairbanks in particular. Seward, Homer are lovely places.
Hope you enjoy your trip.
