It's just foot golf. Orlando has some of the best Disc Golf courses in Florida and since Disc Golf exploded the last two years I'm surprised Disney hasn't cashed in on having a "Disney themed" course nearby.
Based on this bioreconstruct picture where is the future entrance going to be. They cut off the old entrance with new plants but that seems to be the only possible access from this side.
I know its probably been mentioned but the GF to MK pathway having a branch that goes off to the side towards the undeveloped area was clearly not random and will be used for this development. I imagine this is getting announced at the the next D23.
