Hi all, I mostly lurk rather than post... but I want to get your thoughts on this.
I'm getting married in January (so excited!!

). Our budget is a little bit tight, at least relative to the averages proclaimed by the wedding industry, so to save money we're having an afternoon wedding (1pm) and the reception in another room in the church. Based on the church's rules, the reception can't last more than 3 hours, which means that we'll have made the exit to our limo by 5pm at the absolute latest (but probably between 4:30 and 4:45). With this time frame, I would like to just have a cake and punch reception--the guests will have already had lunch before getting to the church, and dinner hour doesn't start until afterwards. Having any additional food will cost a lot of money, as the church doesn't let you bring in any food (you have to work with one of their three approved caterers, and while they're not egregious, they're not the cheapest in the area either). Ditching the caterer also means that we don't have to make agonizing cuts on our guest list because of a per-plate cost--we can celebrate with all the people we love.
So far, so good. However, my mother is concerned that everyone will get hungry and leave. She's not forcing the issue at all--and having read parent horror stories on here, I want to emphasize that this isn't a situation like that! She's just concerned enough that it's making me second-guess my decision a little (even though I don't think she's right). So I guess two questions: 1) there's nothing wrong with just a cake and punch reception manners-wise right? (we will of course mention it on the invitation so that our guests aren't expecting a full dinner!), and 2) my mother's concern is as unfounded as I think it is?
