The first time we went was in the month of May and it was decent.
Still a little chilly but no snow.
We stayed down in Kenai on the river and it was amazing! Got to see the midnight sun.
We also drove down to Homer which was also amazing!
You must eat at Gwennies Old Alaska Restaurant, near ANC airport.

I have also been to ANC in December and although very cold, it was cool to see the sun not come out until 10am and go down by 3pm.
