We are starting to get some replies back...and we've had several of fiance's fraternity brothers indicate that 2 guests are coming...even though the invite was only addressed to one. I guess they are assuming that "and guest" was an option...but it's not, and since we didn't put "and guest" on the invites, I'm not sure why they would think that. How do we handle those guests that assume they can bring a guest? We were very careful to include significant others and make sure that everyone would know enough people to be comfortable, but we don't have the money or venue capacity to add people that we don't even know! These people are our friends, so I don't want to offend or cause any hurt feelings. Any advice is greatly appreciated!
