Wedding Crashers?

Put on the invitations "2 seats have been reserved in your honor", avoid talking about the details with people who are not invited or on social media.

My aunt and my friend had list of people who did RSVP to their wedding and reception, my cousin also had did admit cards and if they didn't have them they couldn't get in

We had one wedding crasher. Apparently she was my MIL's second cousin who drove her grandfather/MIL's uncle to the wedding (he was invited, she was not). I would have had absolutely no issue with her coming to the bar afterwards and hanging out with everyone... but.... she came to the reception, and was dressed completely inappropriately for the wedding. I was really annoyed, but it wasn't worth making a big deal about it. I don't think there's any way to prevent things like that, besides what PP have already mentioned.

I am very nervous about this too! Can you turn them away at the door, or is that too rude?

Personally I don't think that's rude on your part. They showed up at something that they were not invited to. That's extremely rude and you have every right to not let them in.

I actually haven't even announced out engagement on social media yet, I am dreading those "so where's my invite?" and "here's my address" messages lol. I think I might do the admit cards like @Joy B mentioned. For my dads 50th and my sister's sweet 16 we had the addresses on invitations plus RSVP cards mentioning exactly how many spots were reserved, and folks still brought extra lol! People showed up and didn't know where to sit because we had place cards, very annoying! Is it ok to leave off the address from the invites and put the address in a password protected website?

Don't post your event details or make your wedding website password protected like PPs have said. Use "____ seat(s) reserved in your honor" or similar wording on the RSVP cards. If you're having people RSVP online you may be able to include a party maximum for each invitation. You could also have guests "check in" to the reception.

@Nan: I don't think I would leave the address off the invitation because that would be annoying/confusing to a guest. Almost like you're inviting people to something but you don't want them to know where it is LOL. I made my event details private on my wedding website so no one can see them unless they have an invitation & attempt to RSVP online. But I left the address on the actual invitation.

I feel like it would be pretty clear once the person has no escort card and doesn't have a table to sit at? If there's an issue I would just tell your DOC or a staff member at the venue

@MsLaurenRenee You're probably right lol, I wasn't sure how that would look without the address. @MrsCoakleyToBe you would think right?? We had to rearrange tables at my dads 50th because folks were standing there awkwardly since they didn't know where to sit... but we luckily had an extra table prepared just in case. It ended up being full lol. I am hoping people would take a wedding a little more seriously

We're being very clear on our invites of how many seats we've reserved for the guests. We also have a designated person who will issue the place cards. She will have a list of the rsvp'd guests. If they're not on the list, they don't get in.
