So apparently my review was taken down because it wasn't up to standards. So I have decided to write another review that's Yelp worthy.
I've been to The speedway three times, three different years for the Electric Daisy carnival. I went in 2012, 2013 and 2014. Each year has been amazing and the venue is perfect for an event like EDC. The staff was okay every year and we got in and out easily. The traffic the first year was really bad but I think after that year the other two were smooth sailing, well at least for limos.
The venue has a ton of room for different stages and has cooling rooms which are really important for that desert heat. There are also a lot of food and drink stations if you're hungry during your massive partying.
All in all, I hope that EDC continues at the Las Vegas motor speedway, but I have retired!
