Morgan, you mentioned that your parents were divorced. Mine are not, but my FI's are. To say his mom and step-mom do not get along is an understatement. His graduation with both of them there was crazy, and that wasn't for a week! Had it not been for them, I would have said "why not have a reception, or at least a 'free' plan for everyone to hang out the entire evening?" I never would have given it a second thought. Now, however, I realize that that would be a very uncomfortable situation, especially since we have less than 20 guests. I think we may still go ahead and have a short dessert reception after dinner, but I fully expect at least one of them to skip out pretty quickly. What she decides to do at that point is up to her, and the rest of us can hang out and have fun without them. Oh, and we're not doing a wedding cake and we're bringing our own music, so it's still going to be a pretty cheap option.
