As a Guest or Press? Guest I got invited to a really good one over here once and they ghosted me after I responded lmao. Press I'm doing coverage for the biggest one in London at the end of May but not been asked to email them requests and things ;_;
I usually cover the event with just a few tweets/photos. I've heard some cons want you to actually do livestreams or videos but think it depends on the con. I think you'll be alright with maybe a tweet or a thread of photos or something maybe or a small recap on stream after?
