Ideas for a Campus Wide Philanthropy Event

[Binx]

Hey all, I'm a member of my campus' Inter-Greek Council and we're trying to figure out what to do for our next campus wide philanthropy event. Last semester we had a carnival with alright turnout considering this was our first try, we're hoping to improve for this upcoming semester but we're having trouble coming up with ideas, should we stick with the same idea and try for a better turn out or should we change things up a bit?

Any help or advice is greatly appreciated. Thanks in advance!
