A new map has been installed at DTD that shows the area as one contiguous operation as they wisely drop the segregated configuration of the past that only served to confuse guests.
I must say I think this is a wise move as Disney evolves the area into a 'lifestyle center' that does not discourage families from visiting and enjoying the area without the confusion and difficulties of navigating the area that occured in the past.
There are strong rumors also that the individual section names will be dropped for a single name, likely DTD.
So the news is quite encouraging IMO and I can't wait for the final unveil of the repurposed PI area concept.
