Joe,
What changed ?
The critics of Florida golf finally found religion, proving that a little education can go a long way.
In all seriousness, I think the target market changed.
Residential community golf ceased being the primary focus of golf course development.
At one point, people who visited Florida stayed at hotels/motels with golf courses, then a building boom occurred where people visiting Florida wanted homes/apartments in secure gated communities that would insure that their homes would be protected in their prolonged absence, hence the quality of the golf course wasn't the primary focus of that community, with water views being more important.
As those communities increased in numbers and became "built out" golfers sought golf only clubs where they wouldn't have to make tee times five days in advance, accept random lottery tee times and put up with 5+ hour rounds.
In addition, when the economy tanked in 2008, clubs became unaffordable to many, creating a need for daily fee or resort course.
That's my story and I'm sticking to it.
