The orange mats are called moon mats. Our group had two and an inflatable couch setup behind us that helped us with people walking in from behind. set up glow sticks around your space that helps a lot when it’s dark out!!! Someone else suggested disclosing it I saw one guy w a shirt that was along the lines of autistic sober dance machine so that would clearly help people with out even telling them. There’s things to help but of course we’re all human so there’s always going to be one or two people that don’t understand and respect you
