Given the very valid complaints this year about overcrowding, gate-crashing and disorganized entry points, I thought I would add my completely unscientific and personal thoughts on a possible solution:
1) Charge more, sell fewer: Instead of selling 70,000 tix at $260 each, sell 60,000 at $360 each. It's still excellent value for the lineup, and it still represents a small fraction of the cost of attending the festival for the many, many people who come from out of town (or state, or country). You would gross an extra $3.4 million ($21.6 mill to $18.2 mill), which could be used for the following initiatives:
2) Beef up security at the perimeter. You may not need a Glastonbury-style superfence, but you really need to keep gate-crashers out. Word will get around about this year's easy crashing, so expect more to show up next year.
3) Beef up staff at the entry points: Bag check, ticket check, wrist-band issuing. They all took way too long this year and were not ready early enough.
4) Add another route to the parking lots. Instead of telling everyong to come down Jefferson, 3 miles west of the parking lot, encourage people to consider Monroe as an alternative, AND to access parking from the east as well. I assume you have to keep some route reserved fire for emergency vehicles, but surely that can be done somewhere other than the road immediately north of the site.
5) If there's still money left over, some more showers for the campers.
Coachella has (had?) a unique vibe among festivals because of its relaxed atmosphere, manageable crowd, great amenities and tight organization I think that vibe is worth preserving.
