We have been twice during free dining at the end of August and this year am trying the 1st week of Sept. I don't find the head too bad since you are in and out of a/c most of the time or in the pool. I like the fact that it is easy to pack because there are no long sleeves or pants required and 1 pair of shoes for the week (crocs!). I will say that AK was VERY hot and you must go there at opening and leave when you can't take the heat anymore!
