Looking at the layout, it looks like not that much. I live in World Golf Village and am waiting to see how The Esplanada is going to work out, but in looking at the layout of that, I am more impressed. Ben Carter did a poor job at St. John's Town Center, but they have said that they learned from their mistakes, and looking at how they want to lay out The Esplanade, it looks much better for not having to drive to go from one place to another.
I have not been to Nocatee yet, but was initially interested until I realized that the commute to my business in Eagle Harbor was not feasible. I have also come to realize that in the long run, World Golf is likely going to be one of the best places to live in the area. Between the Esplanade and Lion's Gate, the retail aspect will be pretty much covered, and getting on and off the highway is convenient, the best of both worlds.
