I bought general admission tickets for the weekend because I assumed VIP wouldn't be worth the extra dollars, but in the future, I would shell out for VIP tickets.
The main reason is that VIP tickets come with access to a separate, roped-off viewing area that is the closest to the stage. Having a guaranteed spot would have allowed me to show up to the performances a little bit later, and still have a prime spot.
I also was surprised by the toll the music festival took on my body. It was very tiring to stand for hours on end in the crowds, and the VIP area included tables and chairs that weren't common throughout the rest of the venue. This would have offered some much-needed rest.
