Is there air conditioning in the cabin?

Yes there is a combination heat pump/ air conditioning unit in the cabins. We've stayed in 2 of the 3 cabins.

Not sure...but a small portable one with u.

I can't give you a positive answer, but while I was there I noticed air in some of the cabins . So I would say if you bring it you can use it. Or that some of the cabins have air. But not all of them do.
