From what the Conservancy understands from the Chicago Park District, you do not need a permit for a gathering at Promontory Point unless it:

• includes more than 40 people;
• uses a sound amplification system; and/or
• serves alcohol​

The Conservancy does NOT issue park permits for BBQs, weddings, or other events, and it does NOT take donations for memorial benches or trees at the Point. The Chicago Park District and the Chicago Parks Foundation do:
