Funny you put it that way. When it was created it was labelled a "Cultural Chernobyl"Libertine Seguros said:The most depressing place I've ever been in my life was Marne-La-Vallée-Chessy, a new town just outside Paris. And I've been to concentration camps.
I would almost rather die than visit that place again.
I like it though. The trains run on time for one, and crime tends to be confined to the "Frontierland" area on the Western side of the city.
