Distant-ish relative of DH is getting married in August, in Canada. Everyone in DH's large family was sent a save the date card (complete with link to present list) months ago. The problem is that, so far, none of the English side of the family have had an actual invitation (no idea if anyone else has) but everyone assumes that the save the date is the same thing.
I know it's really rude to send out a save the date and not follow it up with an actual invitation so part of me thinks the invites are on their way. On the other hand, though, all the Brits are fairly distant relatives of the bride, have only met her a couple of times at most, and I can't imagine she's even slightly bothered about any of us being there.
There's no way that any of the rest of us want to can go, but MIL and her sister are really excited about it and are looking at booking flights soon. They are both absolutely lovely people, think the best of everyone, and it wouldn't occur to them in a million years that anyone might not end up inviting them if they sent them a save the date card. I've mentioned that they might want to hold off until they get an invite, but they were insistent that the save the date card was an invite so it was all okay. They've apparently never seen a save the date card before so don't understand the difference - though I'm not sure why they think it's an invitation when there's nothing on it that says 'invitation' or gives any details of the time or place of the wedding. I'm worried that they might spend money they can't really afford to spend on flights and hotels and then find out that they aren't actually invited.
How long before a wedding would you expect to get an invitation? I'm not going to say anything again myself, but I was wondering if it would be worth getting DH - who can do no wrong as far as MIL is concerned - to encourage them to wait a bit longer before spending god knows how much on tickets to central Canada.
