As most everyone can agree the parking structure is very "Un-Disney" in the show and presentation. The parking structure is the first thing that many visitors to Disneyland first see. It is very bland and poor show in my opinion. Of course with a parking structure there is only so much you can do to "plus" it. But lets put our minds together and think about the "little" things that can be added to the structure (low level music, murals, Disney attraction posters etc) that will give visitors to Disneyland a great first impression of the day ahead.
I know we can do better with the current "vibe" of the parking structure and I don't think it takes much to make that happen.
Calling all arm chair Imagineers and MiceChatters your mission if you choose to accept it is how you would "plus" the Parking Structure and make the visitors first impression to Disneyland a very special one as opposed to "just another parking garage that could be any mall USA"
