I spoke with my guide the other day and asked if she knew when the path to the marketplace side of DTD was going to open. She made a few calls and called me back (in about 5 minutes) and said that cast members will start staying in building 4 soon, about the 24th of July and then shortly after that the path will open. She said it is ready yet the 4th building needs to be open in order to access it. I am just glad since we arrive about a week after the 4th building is to open.
