If I can't get any money back for the venue, should I just have a party instead of a wedding?
That's a personal choice. I personally wouldn't recommend that you have any memories connected to what would have been a wedding day. But maybe you can give that to a charity, you can say, "You know, we do have this room, we do have this food. Maybe you can have a really nice gathering for your employees." Something like that, just make sure that it's not connected to your wedding. Make sure they just know that you just happen to have this space. Usually, too, most sites won't really let you do that, they've booked for a certain event, and that's what your contracted at. And in your contract it does say what your event is. So you'll definitely want to ask the site about that ahead of time.
