Don't Come Unprepared
The worst thing you can do is not take a look at the lineup before hand. Make a list of who you want to see and schedule it. Coachella is huge and it's going to be crowded. Decide ahead of time which performers you and your friends want to see and stick to it. It will also make things easier when designating meeting places if some of your friends go galavanting elsewhere.
