Activity for Dania

Has anyone else had problems with the app/website lately? I’ve had clusters/an overload of guests coming to our wedding confirming their attendance all at once in the middle of the night or usually around 3pm but when I reach out to them to confirm...

What did yall do when guests started to assume they could bring a plus one or even day of event they showed up with someone you don't even know whom wasn't even invited?
