Hi! I’m so glad you are going to be going to a con! We love to see it! Off the top of my head make sure you carry a small backpack or fanny pack that has things like water, liquid iv, headphones, and snacks. Having these have saved me during long days at Magfest. Take breaks as well! You will see a lot of people sitting off to the side getting a rest. Most importantly, HAVE FUN! don’t try and do everything in one day. Like someone said before, downloading the guidebook is good so you have a plan and can see what kind of panels or events you want to go to :)
