I went on a tour of the new terminal yesterday and I am amazed!
I am biased, and I do like NW, but that place is amazing! The tunnel from councourse A to B/C is incredible, I like it a lot more than the one in ORD. Also, the amount of space, the walkways, number of security checkpoints will be sure to make this easy to travel through.
There are also a ton of restaurants there not to mention stores. The displays for flight informaton are bright, clear, easy to understand and will recommend whether to take the ExpressTram or to walk.
This is a truely amazing facility.
