My fiancee and I are considering a cocktail style reception with heavy hor 'devours and a carving station and pasta station (it all comes in a decently priced package). A lot of our family is older and will need to be able to sit when they want to, but I'm wondering if for this kind of reception whether I really need to make a seating plan or just trust my guests to find a seat where they feel like sitting? The venue would still have a classy, semi-formal feel to it, but with this kind of dining, is a seating chart with assignments and table numbers really necessary? Appreciate any thoughts on the matter!
