I actively refuse to schedule anything. I've been dragged to a few scheduled events and they're all fine and good, but I tend to have the most fun wandering around and finding things. Somehow, when something is scheduled and I spend all day planning to go to it I wind up disappointed. It never starts on time, there's too few or not enough other people there, and it's usually not as cool as it seemed in my head.
When I wander and find dance dance immolation or the life size rockem sockem robots or whatever it is, it's like a discovery.
I'd say pick a few things you really want to see, and maybe circle a bunch that you'll go to if you happen to be bored around that time. Otherwise, just wander. Ride some art cars, talk to people, see some random playa art that isn't on any map or schedule.
