We're having a cocktail reception instead of the traditional sit-down dinner. Our current plan is to have the ceremony at 4:30 p.m. and then the reception will start around 7:30. The time in between, while the venue rearranges the room for the reception, I'm guessing some people may go to eat, but we can't know for sure and we want to be sure to have enough food for everyone. How many appetizers do you think we should serve? I'm thinking 5-7 pieces per person? Is that too much or not enough?
