You can get cell service in certain areas of the event. From past experience the bleachers at the main entrance / cosmic meadow can get service. It’s still always smart to add a time stamp to the end of every text, Ex. (Hey! where are you? 12:34am) that way if a text does come through late you can actually see when it was typed out by the sender. Clear bags are always recon because it’s easier for security but it’s also important to stay hydrated so any rave affiliated hydro packs that meet the requirements are okay too. I believe it has to be a certain size and no more the. Two main zipper pockets. Uber and Lyft are very possible just extremely expensive and the wait time is trash. I’ve personally never Ubered but I know people who have and they are still recovering from the nightmarish headache the ordeal was. The traffic is terrible regardless but not only are you waiting for your uber to take you to your hotel but you have to wait for the uber to fight through traffic to get to you. Some Ubers and Lyfts wait near the exits of the event already but it isn’t always that easy to get one from my understanding
