Both tweets stretch the truth. First of all, if SD posted here he would confirm that there is no single entrance to Disney, there are lots of access points, so Riches, who I helped get banned from twitter, is lying about that.
It is very possible that they did block one access point for Disney Springs, it's at the far end of the property, but it's not 15 minutes away from the closest resort, that's more like 5 minutes away. All of the parks and resorts at Disney are within 15 minutes of Disney Springs, unless you're walking there which they don't let you do.
