The Giraffe trail is very short. The distance of the whole hallway is about equal to the distance between the lobby and the elevators on the Zebra Trail.
The stairs aren't shown on the map, but their occurrence is definitely more frequent. I'm pretty sure there is a set near each bay of elevators, then there are sets at both ends of each hallway (so each wing should have at least 3 sets of stairs)
Since we were on the 4th floor...we favored a set between the lobby and the entrance to the Zebra trail over walking to the elevators.
If you request Giraffe Trail, all the stairs and elevators in your wing will feed very close to the fitness center on one side and the bus stop on the other.
