I started a new job just days before getting engaged. When planning began, I didn't include co-workers on my guest list since I didn't know any of them. We rented a small venue that has only enough room for our small guest list of family and close friends. Several months have passed, my wedding is all planned and I've made some great friends at the office and I'd like them to be a part of the day. We cannot invite them to dinner because the venue doesn't hold more people for a sit down dinner. I know everyone thinks it's super tacky to invite people only to the snacks, desserts, cocktails, and dancing part of the evening, but I think my situation may be slightly different. I'm not doing it because we don't have the money. (I've seen a lot of people commenting that people will be offended and feel like you're saying they're not worth it to pay for their meal) We had our venue contracted for several months before I got to know my colleagues and it just doesn't fit the extra people. In this situation, am I allowed to do the after dinner invite? If so, how do I create a tactful invitation?
