Wedding Planning in Chicago

Hi! I live in Berkeley, CA and just got engaged! We are planning on having a wedding in Chicago where our families can come since many of our family members live in the Midwest and the South and there is a major airport there. Plus, we love Chicago. We are Reform. We want to have one wedding in Chicago, possibly on a riverboat, and with a Rabbi. I don’t know anything about the synagogues in Chicago. We are visiting Chicago for his cousin’s wedding in a couple weeks. Which shuls should we visit for our wedding planning? Thank you for your help!
