That doesn't look like what most photos usually suggest. I always thought 50% or more of attendees were in costumes. I see maybe 1% dressed up in those photos.
Also, while I acknowledge that those 3 photos showing the crowd from above probably don't show the entire convention area, if they do indeed show the entire/or majority of the convention area, it is a lot smaller and less crowded than most photos usually suggest. I always thought it was truly massive, with densely packed crowds.
Those 3 photos almost make it seem like a tolerable experience.
