And I thought of a good analogy: imagine a convention of jugglers. The jugglers aren't constantly juggling for hours on end; they'd kill their arms doing that! They might practice juggling from time to time in the hallways, but only for a few minutes at a time. Similarly, fursuiters go up to the hotel room, put on the fursuit, wander the halls for a while showing the costume off, posing for photos, maybe funning around, and then after half an hour or so they go back upstairs, get out of the suit and hang it up to dry, shower and change.
Thus, fursuiting is like juggling. It's only done for short periods at a time.
