They ended my reception early due to a few people being intoxicated. Without even telling myself or my parents who were paying for the wedding, they turned the lights on and shut down the party 2 hours early. I would check with them about their policy for a situation like this prior to your event.
I loved this room and the staff was very thorough and patient with our needs. The evening got a little rushed and you could tell the banquet manager was flustered, but other than that everything was perfect.
