I moved from a technical a more administrative role because it was the natural progression in the career path I've chosen. So one consideration for you is if you have a future in mind that requires a steady upward progression through the organizational hierarchy. Another consideration is how management would view a declination of additional responsibility. I've had some managers who were perfectly OK with having someone stop at a chosen point; others (in the same company) want only--or primarily--upwardly mobile people working for them.
Is the increased responsibility and availability sufficiently compensated? Will you be comfortable managing those who were until recently your peers? Other considerations aside--from a purely avocational perspective--which would you rather do: your current job or the one being offered?

They've already tried to purchase Disney once before, as I recall. I think there's no question of anti-trust on this; we're talking a straightforward attempt at vertical integration within an industry.
