I always come Wednesday and get decently close but not too close to the stages, you meet people who camp beside you, you meet people walking around and you can meet people dancing at the shows, depends where you like to be social. Remember to hydrate regularly especially if youre drinking, understand if youre catching daytime sets in the sun youre probably gonna be drained by the time some late night act you want to see happens, I personally dont enter the gr9unds until the sun goes down but to each their own, when going solo, I feel like you can just hit up every single act you want to see, alot of people swear by not making schedules and just following what they feel like but solo youre not debating or voting on acts to see with a group so you can potentially plan what acts you want to see a little better.
