How many appetizer servings should I plan per guest? Our ceremony will be at 4 p.m. Cocktails and appetizers starting at 5. We plan to do a champagne toast once we arrive from pictures (6:30?) followed immediately by dinner (6:45 or 7). I want to make sure my guests aren't starving while they wait for dinner, but don't want them to fill up too much on appetizers. How many servings per guest do you suggest for a cocktail time spanning about 90 minutes?
