You can walk from Kidani to Jambo in roughly 10 minutes and it is a very nice walk.  If you would like to take a bus, hop on the first park bus that shows up.  Park buses stop at Kidani first, then Jambo.  However, the DTD bus stops at Jambo first, then Kidani and heads to DTD, so don't get on that bus.  There also is a shuttle that you crab.
