We were supposed to be finished by 11:30, but some guests with young children started to leave about 10:30 and that started the ball rolling for others to leave so we wound it up just before 11 otherwise DH & I would have been the last ones standing (I always thought you weren't supposed to leave before the bride and groom!). Our reception started at 5:30 with the pre-dinner drinks and dinner was over by 8:30ish so there was still plenty of time left for dancing etc.
