So, my parents are hosting our wedding, and FI's family's contribution is the invites (FMIL is a scrapbooking supply salesperson, so she gets stationary for free/majorly discounted). My parents say that it's traditional that the MOB and FOB host the wedding, and the MOG and FOG host the rehearsal dinner. Is this true? If they're already contributing to what would have potentially been a large chunk of our wedding budget, is it wrong to assume they'd be on board with hosting the RD? I don't expect a fancy five star restaurant rehearsal dinner. I'd really be okay with just a barbeque at FMIL and FFIL's house (their house is the only one big enough, since my parents and FI and I are travelling to their town for the wedding). I know it's bad ettiquette to ask someone to throw you a party, but is this an exception (probably not)? Can I ask them very politely if they'd be comfortable hosting a BBQ after the rehearsal? Another option is to have the RD in the church basement (FI's dad is the head pastor, so we're allowed to use the church as much as we want), but would it be rude to ask them to provide the food? I'd be okay with providing the food, really, so this isn't an issue of budget. This is more I'm wondering if it's proper ettiquette to expect, and ask for this. I'd hate for them to be expecting to throw this thing, and end up offended when we do it ourselves. How do I bring it up?
