And this is what the DVC site says, in the Booking Tool:
All Disney Vacation Club Resorts at Walt Disney World are now open with the exception of Disney’s Animal Kingdom Villas - Jambo House which will open July 10. Disney’s Animal Kingdom Villas - Kidani Village is open and welcoming home Members and Guests. Members with confirmed reservations at Disney’s Animal Kingdom Villas - Jambo House prior to July 10, will be transferred to Disney’s Animal Kingdom Villas - Kidani Village. Upon the reopening of Disney’s Animal Kingdom Villas - Jambo House, Uzima Pool will also open, however, all other amenities such as restaurants and merchandise locations will remain closed until the rest of the Disney's Animal Kingdom Lodge opens. A shuttle from Disney’s Animal Kingdom Villas – Jambo House to Disney’s Animal Kingdom Villas - Kidani Village will be provided where available merchandise locations and restaurants are located.
When talking to MS, they indicate they don't know when it will be open, and have been moving people even after July 10. That is after they told me in three calls over a three week period that my reservation at the end of July would be fine because Jambo would be open. You would think they could be a little clearer since July 10 is not that far away. I think they will run out of the right room types at Kidani if they keep moving other reservations from closed deluxe resorts there, on top of the ones from Jambo. And Kidani will be packed, with little QS to speak of.
