Is the venue air conditioned?

I have never been aware of a free, public wifi signal within the venue. There are various password protected ones. If it was there was once open access or appears again in the future, it is something that they do not advertise.
I remember a few years ago there was "free" wifi at the venue. Now whether they forgot to password protect it that year I don't know, but I DO remember being able to get on wifi, and more specifically NOT being able to access it in consequent years.
