I downloaded all of the models into Google Sketchup and modified them for size to get an idea of how I'll be using my space and to make sure everything fit. I'm sure there will be modifications based on Sunrise, etc. Took an hour or so to get everything into the space and another hour or so editing colors and stuff. I was even able to import it into the Polo fields using Google Earth to see the views and how and when the Sunrise and Sunsets will affect it on the exact days of the festival.
I'd be interested in seeing how others plan on using their space. This might give people some perspective on how much (or little) space they'll have with a car. I used a 4 door Toyota Camry but will be driving a 2 door Toyota Solara (sized to scale for accuracy).
