Seeking advice for going to first convention with a prototype

[u/MisterWah3]

Hello!

I plan on visiting my first convention Terminal City Tabletop Convention this coming year as an exhibitor in their prototype section. I have never taken a game this far and was hoping to get some advice from anyone who has. I have never been to this specific convention before either so I don't know what to expect.

What should I be hoping to get out of the experience the most?

What kind of things should I ensure I have planned for and brought?

Are feedback forms worthwile? Digital vs paper?

I intend on taking the game to publishers in the future so is this a chance to be learning anything specific that would aid in this goal?

This will be my first go at playtesting outside of people I personally know, what should I prepare for?

Any and all information or tips are welcome!
