Our venue is very rustic and my cousin is a caterer so we planned to do BBQ and side dishes since that's what she primarily serves. Our guest list has grown to 212 just family and 299 total with friends. Is it outrageous to try and have a full dinner for that many people? We haven't chosen a time so maybe an earlier wedding and appetizers instead of a full meal? I don't know what to do, but it's beginning to sound VERY expensive.
Re: Dinner or No Dinner?
Once cousin spells out the costs, you can figure out what works best. FWIW, most appetizer food is more labor intensive than a simple BBQ meal, and probably won't save you much money. In many cases, apps are more expensive than a simple meal. If you're really tight on the budget, you could just do cake and punch, but that means doing it at 2 or 3 in the afternoon, and it means your reception won't last more than about 2 hours. You'd spend the whole reception just trying to say hello to 300 people.
If you want don’t want to serve a full meal then you need to make sure your ceremony and reception do not overlap with a meal time. Everything would need to start and be finished before/after/in between meal times. If there is overlap then you would need to provide food appropriate for the time of day.
But if budget is such a massive issue, which I am hearing from your posts over and over again, consider having a 2pm wedding, and a celebration 3-6 with a light buffet and drinks. That way you don't have to do a massive bar, full meal and other costly additions. You will be just as married as someone who had a three course sit down.
