You might shoot an email to the
bridal association of the brazos valley, we were at their bridal show this weekend and they had a few venues there that I didn't recognize from our research so maybe they're new and you might have some luck.
Another big space that will be available by then is
the Ice House on Main in Downtown Bryan. We looked at having our ceremony and reception there but the price was just way too high for us considering their setup compared to where we ended up booking (Peach Creek Ranch.)
Hope that's helpful. (Our wedding is next April so we did this dance a couple of months ago.)
