Our venue comes with a 3 hr rental... however, our families love to party and we are thinking about paying for an extra hour. My ceremony will start at 6 pm (traditional Catholic ceremony) and last until 7:00pm giving us about 15-30 min to arrive at the venue beginning at 7:30. The wedding festivities will end around 10:30. I would like an additional 1/2 hr - 1 hr. Do you think this will be too much?
