Does anyone know of a trolley or bus company that will do a hop-on, hop-off type deal for a non-profit event?

Ahhh, I'm lost! :) Does anyone know of a good rental hall for a social event of about 50 people? I'm looking for a dance floor and place for a bar. I'm picturing a Legion or Sports Club perhaps? And if you have any dj tips.. those are welcome too ! :)

Much much much appreciated!!
