Hey all... I have a very minor detail for my wedding next Friday (holy crap!) that I can't quite figure out. We're putting a glass beverage dispenser with lemonade at the ceremony entrance, and I'm trying to figure out how to keep it cool without diluting it (since it will likely be out for more than a half hour). I was thinking of using frozen lemons or something similar, but I just can't envision it. I think my wedding planning brain cells are just ... worn out. Any thoughts?
