Quoted from mrbillishere:
Yeah I have to say, I feel like this was the first year where the main game and vending area got seriously hot late in the day and Saturday night. I recall the small rooms to the side of that room being warm in years past, but this was the first time I noticed that about the main room.
Guess it means more folks are coming out and that's a good problem to have.
I was only there Friday and didn’t notice that it was overly hot in any of the rooms (though definitely not that super-cool A/C feel you get right by the door). But it was sunnier Saturday and presumably the crowd was bigger.
