Ozora 2026 first time

We are going to the next Ozora. May you can help me with this questions:

If we go by car, can we sleep in the car? We can convert it to a "camper". Can our friends camp with us at the samle place by tent?

Can we leave the festival early with the car?

Is there a Lineup somewhere available? I saw kalya scintilla/merkaba, globular, rawar & tribone on the website and want to hear them absolutely! We most likely will not attend the full Festival
