A380, 757, whatever...
Growing up in Seattle, I distinctly remember it was BIG NEWS that the 757 was well overweight (as I, too, have been, but it hasn't been big news). They even had a slogan: "WIP the Weight!", and were asking all the local schools, from colleges to high schools to middle schools to come up with any sort of crazy idea to make the plane lighter.
I guess it worked.
Could Airbus ask all the visitors to Disney Paris to come up with ideas? Maybe some crazy vacationer will have he answer.
