Wedding ceremonies at the Brooklyn Botanical Garden?

Nope, we're not having the reception there, only the wedding ceremony. The BBG offers two options - have a small, private wedding ceremony in the garden at 9AM any day of the week for 350$ (no chairs, no music, no decorations, just a group of people standing in the garden), or have the entire affair at the BBG, including the ceremony and a reception in the main hall attached to the conservatory. Our actual wedding party will be held at the beer garden in Astoria, which hopefully will be much more fun and casual than one held at the BBG - we're not going for anything fancy and are trying to avoid the trappings of traditional weddings and are aiming for more of a picnic atmosphere.
