The place is confusingly organized. There are two big buildings and it's completely non-obvious which levels and which wing things are on. Plus for conferences in which they need to check badges they fuinnel people through a few doors. The blocked doors have guards which could check badges but instead they direct people to one or two doors. The result are long lines and delays. Very bad traffic management.

FUNNY picture: there are signs over all the urinals that warn you not to drink the non-potable water in the urinals and the toilets. As if people would be tempted drink the urinal water if it was potable!
