Purchase one, ten, or wingspan tickets! The more you buy, the less you pay per ticket!
What's a wingspan? Tell the tallest person at your table to stand up and spread their arms as wide as they can. Don't tell them why. Just tell them it's mission-critical. We'll sneak up behind them and stretch a ribbon of tickets from fingertip to fingertip. THAT'S how many you get!
Telling your tall person to sit back down at this point is optional. I wouldn't.
