This was my first ever expo. Had tons of fun playing plenty of games that are out of my price league and some that I've never seen before.
Anyway the question is, Were they using the hotel's backup power generator to run all the games and booths at the expo instead of stressing the hotel's wiring? I noticed it was running when I got there and when I left. I know pinball machines use a decent amount of power but, I didn't think it would require that much.

thanks.
