2013!!!!! First year going. Such a fun experience for EDM fans. Rides, friendly people (once you go you'll probably figure out why), and great water stations. If you're planning to go research on reddit and other websites on things to bring.
I took the shuttle and the wait was pretty bad...mostly because I had to pee and I wanted to sleep and I stayed until the end all 3 nights.
Your sleep will get messed up--I didn't see the strip at night until Monday night because I stayed an extra day in Vegas. Sleep during the day, get electrolytes in, and eat healthy.
Lots of places to sit down and rest up too. That was the only thing I really worried about. Cell phone will not work well, so try not make the huge daisy your meet up spot because everyone is meeting there!
