Wedding canceled. Hmm...

Wow, my wedding season has sure flown by, and now it will fly by even faster.

My last wedding of the year, in October, just canceled. I've never had this happen in the 7 years I've been doing this, so I guess that is good. And I'm glad they decided this before they actually tied the knot. I give them credit for that. I'm really bummed for myself (selfishly..) because this was the wedding at a Greek Orthodox church in St. Louis and the reception at a huge ballroom. Ah well...

Now my dilemma is this. I don't have it written into my contract anywhere about cancellations and refunding money. What do you think I should do?

They put down a 30% deposit to save the date. Part of me feels like I should give half of it back, but at the same time, booking me is like a contract in itself. When I book people, I turn down people. Most likely I won't be able to find a wedding to replace it, and I know I turned down some weddings because I had already booked this one. And I did take a lot of time to do their engagement photos.

As a bride, what would you want? As a photographer, what would you do? As friends, what would you tell me?

**update**
Apparently I don't know my contract as well as I should. At the end of one section I have "Deposit is nonrefundable in the event of cancellation", and since that is what this is, I don't owe them money. Well, that's good. But I do feel badly for them, and all the money they are probably out of. They had some pretty pricey things books. Oh, that's just not good. Not good at all.
