Anything other than table numbers?

I did instruments that I or people in my family play

We did table names. We named them after vineyards/wineries and breweries we had been to together. We got married at a vineyard and met at a beer festival. So it was were very fitting for us as a couple.

We are doing destinations of our dates and to be ridiculous we are putting pictures of us from those dates on them. Most pictures are goofy, this happens to just be a serious one haha. Our escort cards are Hot Wheels so find your car and get to your destination

I have a friend who makes these. Not sure if we will or not use them.

Or possibly these.

I saw people use cities theyve been

We have 200 people coming. I don't want people having to search for tables. Our tables will be numbered in a logical order, so people can sit down quickly.

We did something really weird/cool that our guests loved. We had one bottle of red and one bottle of white wine at each table. We put new labels on them with a table theme. So one was "The Cool Table", one was "The Smart Table", one was "The Party Table", etc. and then we had a little bio on the back about what that meant. Like for the Cute Table, this is what it said on the back:

"Look
at you cuties sitting at the Cute Table with those faces we just want to
squish! You’re hella adorbs, and all around super nice to look at. How on earth
are we supposed to eat around here when we’re all staring at your cute behinds?
We’ll resist the urge to squeeze your cheeks but you’ve gotta promise not to
turn off that charm. You’re truly our favorite people! Don’t tell the others we
said so! We wouldn’t want them to get jealous. Who are we kidding? They already
are!"

And every bottle said something about those particular guests being our favorites and not telling the others. Our guests really got a kick out of them, and it was great that the table numbers doubled as something useful. This worked well because we only had 6 tables. But like Alex said, if you have a huge guest list, it might be kinder to use table numbers in a logical order.
