disney has ESL schools in Shanghai, China. As a teacher who personally emphasizes 'edutainment' even for my university classes, I think the schools will do well, financially and in actually having students leave the school with a strong command of English.
I am of mixed feelings, though, in how I feel about the school. I think everyone in the modern age is suspicious of large companies and Disney just about defines 'large'.
Still, I do expect it to work, regardless of what else it teaches.
