The problem with any Orlando metric is that it's so huge. That number no doubt includes downtown/Heathrow business hotels--and the Rosen and Gaylord--but also de facto homeless shelters along 192. I think, say, the average rate of hotels along Hotel Plaza Blvd. might be a better guidepost.
Please recall that this particular thread started with a discussion of prices charged by Disney's Value Resorts which, from a luxury perspective, are comparable to Super 8 or Motel 6. The hotels on Hotel Plaza Blvd. are not budget motels.
Disney's Value Resorts have different revenue/cost structures than the typical Super 8 or Motel 6. They also differ from hotels on Hotel Plaza Blvd.
Disney's hotels generate a considerable amount of revenue from their food service and merchandise stores, a huge source of profit compared to non-WDW hotels.
Conversely, Disney's Value Resorts costs are greater than typical non-WDW hotels. Disney's hotels need to pay for "free" local bus service, "free" Extra Magic Hours, and "free" airport shuttle. Of course, these "free" incentives are offered exactly so Disney can capture a larger share of the vacationer's dollar. Disney is by no means offering these "free" benefits at a loss. In fact, Disney offers these "free" benefits exactly because they are more profitable than not offering them.
Beyond that, please consider that the hotels on Hotel Plaza Blvd. pay Disney a premium for their locations, a fee Disney's own hotels do not pay. Ultimately, the hotels don't pay this; the patrons staying at these hotels do in the form of higher room rates.
Stepping away from these revenue/cost differentials, please consider that Disney offered these Value Resort rooms for $60/night or less a decade ago. It's important to recall that Disney's Parks & Resorts has never reported an operating loss, even at these low rates.
More recently, Disney continues to offer "Room Only" and "Free Dining" discounts throughout most of the year, and domestic Parks & Resorts operating margin has steadily climbed over the last 5 years while Disney has offered these discounts.
Clearly there are considerable margins built into the current pricing structure of Disney's Value Resorts, more than enough to pay for "Room Only" and "Free Dining" discounts.
In a nutshell, Disney used to make money when the Value Resorts rooms were $60/night. They're making a heck of a lot more today.
