You need the usual stuff mentioned in the previous post as well, but here are a few things I'd definitely add to this list on the eve of my 14th Coachella:
- Lip balm (not sure why this never made the list before)
- A hat (Ibid.)
- The official Coachella app (gets better every year)
- Bandana (or something to cover your face in case we get another damn sandstorm worthy of a Darude-like ninth ring of hell)
- Sweatshirt (or something warm, again, in case of sandstorm. We stood in line at merch for 45 minutes last year due to poor weather and poor planning)
- Tickets
- Hotel reservations
- Phone and charger
- Sunblock
- ATM card, credit card, and ID
- several pairs of shorts
- several shirts
- PJs
- Unna-ma-pants
- sox
- shoes (not good ones, closed-toe, they're going to get dirty)
- medications
- toiletries like toothbrush, toothpaste, contact solution, floss, and for chrissakes, deodorant
- extra contact lenses
- glasses
- music (duh)
- reading material
- camera and case
- $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
