After doing some research on TK and asking opinions on FB, I decided open seating sounds like a disaster. But then I was whining (in my head) because I wanted to use the saying I came up with, so I altered it, and will assign tables.
To get yourself ready
For some fun and amazement
Please find your name
For your seating arrangement.
Set down your key to lock in your seat
Relax, grab a drink
And get something to eat!
I don't like this version as much, so please feel free to give suggestions! And it seems weird to say "fun and amazement," but we have a little surprise for our guests, so it sort of is fitting
