24 hours of daylight will surprise you. It will be more mild in Anchorage or Seward, but warmer and more dry in Denali and Talkeetna. I'd recommend AC where it's available, but as you note, it's not univerally available here.
While other hotels in ANC have AC too, the one I'm certain about is the Sheraton. I hear that the Hotel Captain Cook, while ofthen thought to be the most nice in the city, does not have AC.
A local looking forward to summer too..
Welcome to town!
I toured Alaska last June and July and the weather was really hot! I had my air conditioning on even in the Anchorage hotel. I could not imagine being without one in Fairbanks as the sun was up from 3 am till midnight and it would have been furnace-like in the room if there was no air conditioning. If you can I advise you to book accommodation that has A/C.
And don't forget to pack your shorts - I was glad I didn't as I used them a lot.
You might not need an A/C but a fan is almost always welcome.
