So, what can you bring into the festival? Clear bags made of plastic, vinyl, or PVC are all good to go, as long as they're not bigger than 12x6x12 inches. You can also bring in small bags like clutch purses or wallets, as long as they're not bigger than 4.5x6.5 inches.
But don't even think about bringing in confetti or noise-making devices - those are a definite no-no! And, of course, no outside food or drink is allowed, unless it's a refillable water bottle. You can, however, bring in empty water bottles and fill them up at the festival's water stations.
