I’m going to Six Flags: Great America on May 21 for a school trip. I was going to get a Flash Pass for my friends and I but I don’t know if there’s an age limit for buying one because I’m only 15. From what I understand as long as you have some sort of collateral to leave when they give you the unit you can buy one but I’m not sure what’s acceptable for that. Could someone please give me an answer to this?
