Red = New Water Park, based on either POTC, or Neverland
Light Blue= New parking structures
Blue = Disney's Third Gate
Black = New Hotels at Garden Walk
Yellow = Hotel themed to Water Park
Lavender = DTD expansion on the east side of the parks heading towards the 3rd gate
Green = New expansion with the Disneyland Resort Monorail that goes from the current DTD Monorail stop to a new stop right in front of the third gate
Orange = Cars Land
I think I would prefer the idea of TDS or DAK or WESTCOT for the 3rd gate, but I'd most prefer something completely new that still says disney, like a Villain's Park, or a Worlds of Disney idea with one area being toons, and others having heroes, villains, kind of like Kingdom hearts, those would all be options I'd like to see.
Also please look below at my DL park expansion and DCA expansion maps with many new rides.
If you need me to clarify anything let me know, otherwise, please comment.
