I would go ... and enjoy yourself ... just set it up with your friends that if they have something they want to see, that you not let it hold you back. I'd take the wheelchair, and when I went to the booth to see, I'd have a cane with me so I could stand up a bit and so that you can better without having to fight it ...
I'd play it by ear really :D GO HAVE FUN :D TAKE PICS! :D
