I feel your pain y'all! We made sure the singles knew they could invite their significant others and we're only inviting family so I didn't think we'd have to deal with any of this when I started getting RSVP's through our website of people we'd never heard of (its password protected so it was only family viewing it). It turns out the FI's single cousin had decided this was spring break and instead of inviting his girlfriend had invited a bunch of guys!!! Ummmmm this is NOT ok!! I told the FI he better nip it in the bud (especially when family members hasn't even booked yet) because if he thinks for two seconds this is spring break he has another thing coming! Lucky me, I robbed the cradle and sometimes he's still a 12 year old, but I've told him that if he's drunk the entire week I'll turn and walk the other way when I get to the top of the aisle!!! Lololololol! Is that bad? I just don't get the nerve of some people! I would NEVER invite myself or book a trip to someone's Family-only wedding, especially not knowing either the bride or groom! Insane!! Lol
