I am having a budget, DIY, causal wedding. I have a question in regards to the amount of cocktail hour food. We are having the ceremony/reception same location in a friends back yard. we will just be going to the front of the property (LARGE PROPERTY) to take the photo's during the cocktail hour. I really do not see it lasting for 1 hour, but you never know and that is what I planned for. We have about 110 guests. I am having just a round table for the cocktail hour food do you think this will be enough....crackers/cheese, veg/dip, antipasta salad and like 15lbs of jumbo shrimp. I am worried people will be hungry and say to themselves "is that all she is serving" lol....what do you think I cannot afford to have butlered service should I add another item?? if so what
