Coco would actually have some Mexican cultural significance....which Three Caballeros does not...
THe parking alley on the left side of the pavilion building appears to have a lot of space....Perhaps the attraction queue could begin outside the pyramid out there on one side or other of the existing show building ... for the bulk of the queue and then the last portion enter the main building.... I mean I am sure there are reasons why this could not work, but if they wanted to make it work, they could....and it would be a great addition to the park...that still needs more attractions.....
