I'm in a dilemma. I'm inviting a few old friends who I would love to attend my wedding (high school & college friends). However a few of them are single, and to my knowledge aren't dating anyone super serious. We're having a small wedding, only 60 people, and 60 people is the absolute max, any more then that and we would literally have no where to put them. It's a rooftop wedding so the space is small and limited.
I'm not exactly sure how to approach this, do I ask them personally not to bring dates? My fear is that they will assume that they CAN bring a date, and then day of the wedding they just show up. I don't know how to clarify without beig rude or offending anyone. Any advice would be appreciated!
