Provide your opinion on the design of the Great Hall and how it affects people's travel experience.
Actually, the entire Great Hall will not be behind security. One half of it will be in security with all of that ridiculous retail/restaurant crap that we will have to traverse through (and won't be used as much as they think) and stumble over each other because it will be too cramped with people trying to get to their needed train. The other half (by the Westin) will be open to non-screened people waiting for arrivals or whatever, and will have other restaurants/retail. That side  will be a ghost town for a lot of the time. No matter, we agree though, the whole design is dumb.
