You click the button for the first floor. When the door opens you see the Ocean Hall. Just past that is the Rotunda, and the elevators you need to get to. You sneak around the Ocean Terrace Cafe in an attempt to avoid the cameras. You head through the Mammals exhibit, close to the elevators. You hear a sound coming from the gift shop as you pass. It is an employee stocking the shelves. They quickly call over their radio that someone has broken in and the police are called. You were so close, yet so far.
