Specifically in terms of food.
My fiance and I are paying for the rehearsal dinner, a bridesmaid's breakfast, and the reception. My question is in regards to the after party and a Sunday morning brunch. I was just going to reserve a space at a local bar and a local breakfast buffet (respectively) and extend an invitation that if guests were interested they could join. Would it be rude to ask guests to pay there own way for these events?
