Ok, so there are a ton of threads on "Un-invited Guests" and how they are irritating.
FI and I are very much "the more the merrier" type people. Even in our home, if we're having a bbq or something, we don't mind if you bring someone.
Well, with our wedding, I guess we are the same way...We were at a very close friends house and his SIL and BIL were there. We've met them a few times and they are pretty cool (and fun) people. So we verbally invited them and when it comes to invitation time, we'll send them one. After getting over "we aren't really invited" and our friend reassuring them that it's ok for them to come, they booked their tickets. I guess they mentioned it to two of their friend and they asked if they could come! Our friend told them he'll check with us, but as far as he knows us, we won't mind. And we don't.
FI's mom's best friend...apparently her MIL and SIL want to come. I've never met these people, but again, I don't mind. They even said that they don't necessarly want to come to the wedding, just to Mexico. We told her that of course they can come and if they are coming that they will be invited to everything and treated as any other guest (welcome dinner, wedding, OOT bag, etc.).
FI and I are talking about having a "Margarita Party & BBQ" sometime in Sept or Oct (if it's not too cold out) for all of our local already booked Mexico guests to get together adn meet each other before heading to Mexico.
I feel like we're the only bride and groom who don't mind this...
