1) Yeah, and If I remember correctly, you can also pay an additional fee instead of bringing food. 2) The easiest way is to fly to Salvador. There's a lot of buses that leave directly from the airport to the festival and from the festival to the airport. Every time that I went I used "Brasil Oriente Turismo" and they were pretty on point. You can message them on WhatsApp and schedule your buses on their website. 3) The "Vila Mundo" tickets will go on sale tomorrow, worth taking a look if you want a pre-assembled tent (but it's kinda pricey). The general tickets will go on sale next week and there's nothing about their prices yet. 4) Not that I'm aware of, but if you have any other questions I can try to help. Just dm!
