I need help

So as most of you know I am in charge of planning enrichment activities for our ward. We are planning a super saturday for october and the only problem with that is I have never even been to a super saturday. I guess avoiding extra church activities for my whole life has come back to bite me in the bum. So if any of you have any great ideas for me I would love to hear them. I need help... what is the funnest or most useful thing you have done at one of these shindigs?
