What's your take on golf?
That's a tough one. Golf Pros should design golf courses. So, from that aspect, Disney has no business designing them. As for operating them, I'm torn.
See, my baseline is 1971 (and subsequent years of development). Disney moved to Florida, developed a huge plot of land, built a theme park, built hotels, and implemented a vast array of activities, recreation and amenities.
Along the way, they added things like golf courses and kennels and car care centers. Some of those things are just courtesy items, to make each guest's stay on property that much more convenient. Disney doesn't run the car care center, and they don't need to, but it's a great asset. Same for the kennels.
When most people hear Disney, they think first of theme parks, followed by their reputation (while currently arguable) for the best in customer service. When people think of Disney World, most don't think of Disney as an entity known for running great kennels or golf courses....but for operating world class theme parks and hotels. Those two things are the core of what I, and many others, hold Disney accountable for.
I know my comments won't go over well on here, but it's not fair for us to jump to the conclusion that every thing Disney "takes away" or "outsources" is strictly because of money. Yes, that's part of it, but in a more global aspect, it makes better business sense to let professionals run certain things. It's not always better to try to do everything yourself, when there are people who can do it more effectively, while also doing it more cost effectively.
