Great place for business for sure.

Great place for business for sure.
You need to be physically very active because the expo is enormous and you need to walk everywhere. Make sure you wear sneakers!
Also you need to be able to make a sacrifice with you food regime - the fast food on premisses is really bad. McDonalds in Building C feels like a Michelin restaurant :)
Avoid coming and going with the crowd in the popular morning and evening hours - the subway is packed.
A good thing is that the pass for the expo is free. I ve registered mine online.
Overall - an interesting experience!
