It's not a question of whether it's a good deal, it's a question of whether most of this redo is even necessary - IT'S NOT!  Changing the look of the great hall to all of that wood trim is just silly.  The terminal has a modern futuristic look of glass, steel, shiny marble and tenting - the wood looks out of place.  Moving a TSA checkpoint upstairs to level 5 is ridiculous - the great hall doesn't need more commercial space, no passenger has the time to use it.  Move one checkpoint downstairs to where the train empties out.  Then extend the giant train escalator to exclude the weather elements at the top - glass it in.  And spend the rest of the money on automatic trams to shuttle car rental and distant parking lot fliers to their off-site locations.  THOSE are the improvements we need.
