Hmmm, I think 70 people might be pushing it for the inside area. The contact person at Indian River Shores is Laura Aldrich. I forget her email offhand, but if you google Indian River Shores Town Hall, you'll find her under town clerk. The have a limited amount of tables and chairs that you can use inside. Unfortunately since we're planning on having everything outside we're bringing everything in from a rental company, but at least I won't have to worry about setting everything up and taking it down. Hope this helps! If you want to see pictures of the place email me at kmsander04 at yahoo dot com.
