Respectfully, additional retail space in DTD does not represent improvements to the theme parks. Essentially, Disney is taking their existing mall and making it bigger. I suspect most of us already have several malls closer to home.
Iger and Rasulo build timeshares and stores because they can tie it directly to revenue. They don't 'get' theme parks.
Projects such as road improvements generally are lumped under capital maintenance. These projects are counted as capital expenditures (capex) but are expenditures needed to keep the facilities operational.
In 2013, Disney spent $2.1B on capex. Most of that (at least 2/3) was on Furniture, Fixtures & Equipment (FF&E) or capital maintenance. P&R revenue was at $14B. In other words, Disney spent 15% of revenue on capex.
For comparison, Eisner averaged over 25% before 9/11.
Last year, Universal's capex came in at 26%.
Organizations that are actually investing in their theme parks are spending north of 20%.
Iger and Rasulo are at 15%, with most of what could be considered true investment dollars this year being spent overseas in Shanghai.
Iger and Rasulo have never appreciated WDW's real potential. When it comes to WDW, they'd rather coast.
