Other mistake: When the girls go meet Mrs St Claire and schedule their dates as they are leaving they tell the other bride walking in that there is 1 date left available in June at the Plaza. Mrs. St. Claire would've told that bride the last remaining date was June 6th. Therefore, if Angela messed up the bookings hen the other bride would've already thought her date was in June 6th, and then she would not have disagreed to changing the date, because she'd be changing it to the date she originally thought she had.
