Our venue has a 9:30 pm cut-off for music/sound system due to a local county noise ordinance. It's a summer wedding, and if there were no limit, we'd love the party to go to about 10:30 or 11. Would it be tacky, or a bit of a bummer, to switch to a silent disco at 9:30 pm to let the party go on? What are your thoughts/ideas?
