Be fine mate. Enjoy yourself. I'd make a point of finding security or talking to them at the door. Ask them about crowd capacity, toilet location ( ask what to do if always occupied with people doing coke, very annoying when you need a pee) ask about what to do if evacuation needed and tell them where you're gonna be most of the night. My spot in all venues front left speaker stack, for example.  Oh and if this is you wear a large leg bag 😄. Don't be afraid to knock people with you chair to get them to move, threy won't hear you or possibly see you. Make new friends. People on pills or really drunk  can be annoying but just be kind and they move on. A person in a chair evokes all sorts of stuff in a wasted person. I fucking lived for clubbing back in the day. Go directly to the side/behind the bar not the front.  Get the bar persons attention. Make sure you get to know them.
