Please excuse my ignorance, but what exactly is a Cub-O-Ree? I've been to a Webelos-O-Ree, but that was an overnight event. I imagine you wouldn't be planning a District wide overnight for boys of all Cub Scout ages. Is it a day long event? How many boys do you expect? What time of year will it occur? Perhaps with more information, you will receive more suggestions!
Thanks,
