We are having over 150 guests at our beach wedding ceremony in April. The officiant said it should last no more than 15-20 minutes. Is it classless to have all the guests gather around a marked runner instead of paying the extra cost for chairs? We are already over our budget and figured it would be an easy thing to do without, since chairs come with the reception but not the ceremony. I was also thinking of possibly getting a few benches or 1/2 chairs for grandparents, pregnant friends, etc that cant be on their feet very long. I dont want to be disrespectful to the guests, but chairs are very expensive. Thanks!
