yep it was extremely chaotic.
1. don't plan on buying any food and drink there unless you have $$$ to burn and non-functioning taste buds
2. practice 'holding it'. the female toilets on the 1st floor refused to flush
3. if your summer tan is starting to fade, head to the elly lukas tent out the front to get a free spray tan (yes one girl from my school got a full body spray tan today! - me, i just took advantage of the free manicure and back massage)
4. there didn't seem to be as many cool freebies this year

i didn't even get to scam many free pens
5. if you're planning on attending any of the seminars try and get there early as they ended up putting security on the escalator to stop too many people heading up
