I did ask for ideas to fill those spaces and didn't think of announcing the t-shirt pickup. Next year...
If you want to use those booths, then use them to give away the old t-shirts next year. I would not give out old tech or a/v shirts though.
There were 4 people at the booth giving the t-shirts out, along with phones to record that they were given one. I am not sure of how many people it saved at registration.
