Greg B, ordinarily the 'open a window, yer idiot!' option would work in Nova Scotia, but this weekend it was 35C and humid in the centre of the province. I am not built for the tropics, but managed (not having generator powered AC myself) by soaking my straw hat with water once an hour - very cool.

Most festival sites here don't have hookups. I'm greatly in favour of this generator user segregation idea; I'd really like to see it catch on.
