My fiance and I are Christians and a big majority of the wedding guests are too. My fiance brought up that he would like to do a blessing of the food when the reception starts. Now how I thought to do this is ceremony starts at 4 pm, ends at 4:30 pm, guests go inside to mingle and explore the venue until us and our family is done with photos at 5 pm. We are not doing a cocktail hour for the guests during that time due to budget reasons. Us as a couple would like to get our food first and then the prayer be held then other guest may join the buffet line to get food. I need opinions/advice/options on how to do this or how others have done it. Is 30 mins too long to have guests mingle and wait to eat?
