Disney Vacation Club has officially released very little information about the new Copper Creek Cabins & Villas, so most anything said at this time is speculation.
An opening date has not been set for Copper Creek. The Notices of Commencement for the work at Wilderness Lodge filed by Disney extend to April 2018, which is why most people believe all the renovations won't be finished until then. However, its possible that parts of the construction might be finished much sooner than 2018. When Disney converted some of the Polynesian Resort to DVC villas, it opened the renovated rooms in phases: The first Longhouse opened in April 2015, the third Longhouse opened in July 2015, but the renovated Oasis Pool was finished until March 2016. The same staggered opening might happen with Copper Creek.
It would not shock me if some of the new Copper Creek villas might open by June. But it also wouldn't shock me if the villas don't open until late 2017.
DVC has said that Copper Creek will be a separate condo association and not part of the existing Boulder Ridge Villas condo association. Since it will be its own condo association, it will have its own
point chart and own set of points. In all likelihood, the Copper Creek villas will cost more points per night than comparable villas at the existing BRV. But that is just an educated guess on my part.
Good luck!
