Where to host a wedding shower in Lafayette, Indiana?

I am trying to plan a wedding shower in Lafayette, Indiana or the surrounding area. (we could go up to 20-30 minutes outside Lafayette.) It will be Sunday, May 1. I am not from the area so I do not know what is available. We are pretty flexible, could have it at a park, banquet hall, church,etc. I would prefer not to have it at a restaurant, I don't want the guests to have to spend money. We would like to spend $50 or less to rent a place. We are thinking 20-30 guests. Thank you in advance for any suggestions!
