You don't have to take the bus, you can walk it.
10 minute walk at a leisurely pace.
Edited to add: But if you DO take the bus, make sure you ask the bus driver before getting on if it's going to Kidani. When we were there in 2010, most of the buses picked up at Kidani first and then went to Jambo... so if you just hop on any bus without checking, you might end up at a theme park rather than at Kidani.
