I went to Alaska on a family vacation a few years ago. It's absolutely beautiful there. I was there in August when the weather was in the 60's. Also, it never got dark outside which was really weird. I have trouble sleeping unless my room is pitch black so imagine it being midnight and still bright outside.
I had never seen "purple" mountains before (like in the "America the Beautiful" song) until I went to Alaska. Make sure to go to Denali National Park. We took a bus tour and I got to see all kinds of wildlife up close. We also took a boat tour of glaciers. That's the only time I remember freezing my butt off while I was in Alaska. Besides that, the summer weather there is very nice. I just wouldn't advise going there during the winter.
