So, you have spent hours, weeks, maybe even months planning your reception ... meticulously choosing the flowers, linens, and cutlery. And most importantly, you have tasted cake ... lots and lots of cake (yum). You must, and I repeat must, document the beauty.
Carving out some time in your wedding timeline for the photographer to document the reception area before the guests arrive is a great idea. If at all possible, have your guests enjoy cocktail hour in a different location.
