I have been twice and it is sensory overload to say the least. You need at least 3 full days to see most of the things that interest you. There are many different vendors selling car and non car related items ( even pinball ) Unless you are bidding on vehicles, I found the actual auction didn't hold my interest for very long. Many food vendors inside and outside to choose from. It is definitely a must see. Enjoy.

I believe that when you arrive, the parking staff will direct you to the parking lot area. They have a shuttle bus that comes around and will pick you up and take you to the entry area. I don't think there was a charge for parking the times I went.

Also Russo and Steele is just 9 miles away . Wednesday January 18th for the auction preview and the auction starts Thursday January 19th. It is another great place to see some very nice cars.
