vip areas should (and do) normally include
1. seperate bathrooms
2. seperate bars / food
3. a vantage point to watch the bands from, not always close, but usually raised up (or on a hill, in Coachella's case) so even the shortest of folks can see, maybe even while sitting.
VIP is maybe the wrong term, but it does let you enjoy the concert, without feeling like you're right in the middle of it.
maybe VOP = Very Old People
