Why I'm giving all my wedding guests +1s

Right now, we're at the point where we're addressing and sending out our Save the Dates. I was trying to figure out the best way to include "and Guest" on the envelope, so I searched around. You know what the answer I got everywhere was? "Ask your guest their partner's name!" and "Guess what! You don't HAVE to invite people to bring a guest you don't know! Yay!" Not helpful.

Believe it or not, we decided way early on in our planning that we are totally excited for people to bring people we don't yet know to our wedding.
