Any tips for first-timers about putting on cosplay in the convention center? I heard there's an area to do that, to check in a bag, and repair if anything rips or breaks. I'm planning on a cosplay that has several parts to put on and it's big but not like Gundam big. I was told either park in the lot and put it on there or bring it in a suitcase and find a non busy spot in the hall. Any tips?
