I have 3 bags that I want to wear as part of an itabag/ultra-fan outfit/costume. I like to use 2 of them as display-only, and actively use one of them for holding my phone/snacks/etc. They are not bulkier than normal bags and I don't take up more hall space than a person in a costume with my ensemble. None of them have wheels and all will be under my control at all times.
Is there any way I can take my two display-only bags to, say, Weapons Check and have them officially cleared and ziptied-shut by con staff so that they don't have to be checked at every door entrance? Can I ziptie them shut ahead of time?
