The whole how to get people home thing did occur to me, but there's a large B&B about a 5 minute walk from the potential venue. And like I said, two of my Aunts also live very nearby so presumably, at least some out-of-town family guests would stay there. My bigger concern would be my friends who would be coming from the city, as there's no public transport at that time of night into the city so I'd feel bad about them having to pay for a hotel. But they might have to do that anyway, even if it were a different night.
And yea, yea, Cali Girl, I've seen that on OBB. Thing is, I think not being considerate and courteous to your guests IS tacky. And, to me, that makes things like cash bars and addressing your own envelopes for thank you notes at showers tacky while things like red wedding dresses just fun. *shrug*
