We are having 150 guests and the chapel vestibule is too small to accomadate a receiving line. We would have to do one outside of the chapel. I'm really thinking about skipping it altogether. My fiance` does not have an opinion and says it's up to me. I've read "The Knot's" perspective, which says- its a polite and proper way of ensuring that each guest gets a personal greeting. I'm iterested in your opinions. Is this a must have feature?
