I regularly compare Disney's P&R segment to Universal (what Comcast tells us) and SeaWorld, and their revenue numbers generally look comparable when you adjust for their # of parks and # of hotel rooms.
I've never gotten the sense that there's a massive overstatement there, but there could be some issues in the $50-100 million range in terms of backtaxes owed on some of these things (i.e. complimentary items being counted in revenue, gift card issues, etc.).
I just don't get the sense though that the $6 billion number being thrown around is a realistic number though.
