AKL Jambo shares buses with Kidani, and some also with Blizzard Beach. I thought it was only the AK park bus that shared with BB, but in March we had breakfast at Boma & took the bus from there to DHS - and we made a stop at BB.
The buses stop first at Kidani and then (assuming they aren't full) stop at Jambo House. They don't stop at any other resorts after this- straight to the parks!
