Golden Oak was expected to sell like hot cakes, necessitating a Celebration-Esque lottery or response. That did not happen. Golden Oak has maintained steady growth and yes, the Four Seasons is thriving (despite its location in Golden Oak, I do not consider it to be a part of that. Also able to prove the point is STK which has had low numbers since opening. Yes, Orlando has money as proven by neighborhoods like Isleworth, Lake Butler Sound, & Keene's Point, but the Disney fan base with a lot of money to burn is not in Orlando. Finally, if you compared the number of high income families is the Greater Disneyland Area (Anaheim, LA (which has a multitude of rich neighborhoods such as the Hollywood Hills and Bel Air), San Diego, etc.) than the greater WDW area (Windermere, parts of Lake Nona, maybe something in the Tampa area).
You are more than welcome to dispute this, and I very well may have all of this wrong. But, while making money, isn't a resounding success.
