Having stayed in a number of hotels, but by no means an exhaustive amount, microwaves and mini-fridges are absolutely no guarantee. You're more likely to have a hair dryer bolted to the wall and a small single cup (though still loose ground based) coffee maker than the other two.

I suspect the air conditioning system would be present even in Alaskan hotels.

It wouldn't surprise me, my American relatives use a tumble dryer in Arizona.
