My site charges $50/hour for decorating/rehearsal time and $275/hour for the event. My fiance and our wedding party and parents are arriving 3 hours before the wedding to decorate and are also planning on having our photographer bust out a bunch of the photos. The venue says we have to pay the full event fee instead of the decorating fee if we are being photographed. Is this crazy? Should I negotiate the lower rate for these 3 hours? Thanks!
