We recently moved our park wedding from 3:00 to 4:00 to avoid the heat. It's a fairly casual, 30 minute wedding, and since we're on a next-to-nothing budget, we only planned to have a cake & punch reception. Now my mother is saying that because it's so close to 5:00, we'll need to provide dinner as well. While it's a nice idea, it's not particularly plausible given the budget and The FI is balking. Can we just stick to our cake & punch plans, or do mom and etiquette win on this one?
