I have to make the reservation for our venue (ceremony and reception in same room) this week, but I don't know how long to reserve the hall for! Our reservation time must include set-up/decoration time and clean-up time and there is a 4-hour minimum. Decorations will be simple, but I'm not sure how long they will take. The ceremony will begin around 6:45pm (invitations will say 6:30pm) and the reception will end at around 11pm. Any advice or recommendations about a DIY set-up and clean-up time frame? How long should I reserve the hall for? 6 hours? 8 hours? Help!!!
