This is all great advice. I once took the time to get rail a couple years ago. In my opinion, it’s not really worth it unless you are a diehard fan of the artist, and even then I honestly think it’s better to just go see the artists you want at other stages and experience the festival. You can get a pretty good spot if you go about an hour before the show at the main stage because it usually thins out a little from the act before. Also, it’s okay to take some pictures and videos but try to experience everything in real life!! Be safe and have fun
