One small addition to your very creative list of must do's.You can use the elevator so at CR go up to 11 and look down to the lobby, cool huh?
Blt has those great windows so go up and check out how nice that is.
If you hit the 11th floor to view the Atrium lobby consider walking out the North west Fire doors near room 4748 to view the MK at altitude. High above the 4th floor viewing area.
Note: You might walk up to the roof for a more expansive view on the same stairway.
