I'm just wondering if I need to do this? Maybe for the rehearsal dinner but we are having the wedding dinner at 5PM and I know that he will need to say mass at 5:15 so there's no way he'd even be to the reception until 6:30 at the earliest and we'll be done with dinner by then. Is it just a a case of telling him after the wedding that he's welcome to stop by? If he was there for dinner I'd need him to fill out a dinner choice but I know he won't be there for that.
