Yep I asked the lady to let me go up and took a panoramic picture.  I'm glad I could go in before opening time to take pictures before the show was full.  I have to say that every time, the Claas exhibit is my favourite.  I think you are right, around 150 people upstairs (VIP customers) and the other upstairs was for catering services for the people working on the Claas booth.

The Deere guy I talked to told me 7000 sq metres of display.  That's 1.7 acres!  At the price they rent space, that's close to a million euros just in rent.  Deere spent 4 million euros just to rent the space and set up their exhibit (plus a lot more money for staff, food and booze, etc.)
