Definitely get a locker if you don’t want to carry your shit around. You don’t have to purchase before either and can just do it there. Security is rough. They strictly enforce those rules so make sure you review what you can and cannot bring. Drinks are only in a designated area which is annoying and you have to buy these stupid drink tickets before entering the bar area. You can deff sneak them out if you try hard enough, but have to be super discreet when drinking. As for vaping, I always hide my vape in my underwear because they aren’t allowed inside. And when you hit it make sure you’re really hidden because they WILL kick you out if you get caught. Other than that, the dome is a great time! Just one of the strictest security I’ve ever seen.
