My fiance and I are paying for over half of our wedding and are still in school, so we're on a pretty tight budget. I don't know if we'll have a rehearsal or not, but either way, pretty much everyone is from out of town, so I'd like to have some sort of get-together. But if we can't afford to buy everyone dinner (even pizza sounds a little daunting - it would be close to 30 people), is it okay to just reserve a room at a restaurant everyone can afford and tell them they're on their own? I'm worried that otherwise, we might not all get a chance to get together...
