By the way TOT was advertised in Austria, but not by Disney. Ford ran some commercials about Disneyland Paris over here. Back then that company was a sponsor of the resort.
I also don't have a problem that the park mainly uses English and French. I think that's enough. There are guides available in all kind of languages that provide informations.
A friend of mine had the opportunity to talk to an employee of DLP. He told him that Disney made surveys in many European countries and that Germany didn't respond well on DLP. That's one reason why it wasn't advertised more.
