The regular tour is $20 or less depending on if you buy in advance. I enjoyed it. No, you don't get to go on the floor but just seeing the inside of the insanely massive facility was a good bit of fun.

But a VIP tour would be amazing. I saw a lot of things I wanted to see up close not to mention just to be on the floor and truly get the scale of the building.

Enjoy! I'm super jealous.
