From the Disney Parks Blog:

Our multi-year transformation of Disney Springs is continuing, and as you know, we’re bringing new experiences to the West Side Neighborhood, including The NBA Experience at Walt Disney World Resort. Today, we wanted to share an update that to make way for this basketball-themed experience, the West Side area will be undergoing changes – beginning with the closure of DisneyQuest on July 3, 2017.

Until July 3, DisneyQuest will continue to offer a great interactive experience for all guests. Disney fans of classic arcade game favorites and virtual worlds featured at the indoor theme park are invited to come out and enjoy the experiences.

As we’ve previously shared, The NBA Experience at Walt Disney World Resort will be a one-of-a-kind basketball-themed experience featuring hands-on activities that put guests of all ages right in the middle of NBA game action. There will be immersive NBA video productions and numerous interactive experiences, as well as a restaurant and a retail store.
