Thanks to the Haihe Water Conservancy Committee of the Ministry of Water Resources, we have our first look at the layout for Legoland Beijing:
Of course some of this layout could be placeholder and some or all of it could change. Certain parts of the layout are easily recognizable such as the Brick Street entrance area, Legoland Creative World in the center, and even some individual attractions.
The areas labeled 1 are for "theme park, commercial street, etc.", the areas labeled 2 are for "second gate park", the area labeled 3 is for a hotel, and the areas labeled 4 are for parking.
