As told by many boat drivers from riverside/fq last week, the treehouses have been shut down for a few years now, but they are not possible to be used as part of a resort, they don't have disabled access and they're built on protected land, meaning they can't change the build design to make them accessable for disabled people. However they have been re-furbished and are going to be used to house the college students, which is pretty cool, they look nice, i'd like to stay in one. One of the boat drivers seemed to think some of the villas are being used already.
And now for one of those usless facts - The lights of the treehouse villas are left on to help the boat drivers navigate the waterways.
