Convention Schedule plug-in?

I was hoping someone could tell me if a plug-in exists that allows you to create a schedule for a convention that covers multiple locations.

Specifically, I organize a small gaming convention and would like to be able to create the schedule through WordPress without having to change around the HTML whenever I need to make a change. Ideally each game table would have its own column, and each row would represent a one-hour block.

In any case, if anyone could point me in the direction of a module capable of doing this, I’d be most grateful.
