Going to / from fest

Doing a hotel this year and trying to plan how to get to / from the fest! I know camping grounds are huge. Really just want to get closest to the fest as possible. Options: rent a car, park it everyday, how do you get into the fest from there? Uber get dropped off again is that a long walk into the fest? Or just do shuttles/ how do the shuttles work? Appreciate literally any info!!! 💖
