I know it was a surprise to the mom-to-be, so I'm thinking that maybe it was the parents/her husband who hosted it. Apparently, it went well. I sent my gift along with someone who could make it, and I got a text at work saying that she loved the gift, so I guess I'm in the clear. I don't know if anyone else couldn't make it because of the change or not, but all's well that ends well, I guess!
