Look at the weather and personal habits. Because the music festival is very long, I wonder if you will be tired. Anyway, I think you must bring something to sit on the floor, such as a blanket, and lie down and listen when you are tired. Of course, if the venue is good, you can sit on the lawn and lie down. At the beginning of the music festival, it was sunny and most of the time was in the evening. There is no need to bring sunglasses and a hat. It's easy to fall off when it's really high. Then the money, right? Water and food. The music festival takes a long time, so we have to go to the park for dinner during the break.
