Invitation question
Re: Invitation question
Yes. Their prior engagment may fall through.
Re: Invitation question
yes, even though you know they can't come, it's still proper to send them an invitation since they recieved a save the date
Re: Invitation question
If its due to religious observance, that will not change. I'd definitely count them as a definite no, but if you have enough invitations, it couldn't hurt to send one. I don't think they'd be offended though if they didn't get one under the circumstances.
Re: Invitation question
No matter their reason for not coming, they should definitely receive an invite. We had a lot of people tell us they couldn't come to the wedding when they got the STD, but most would have been offended to not receive an invite.
