Check to see if there is an early breakfast bus when you arrive to check in at SSR.
The DTD buses will not start running early enough to get yo to the AKL in time for a 9:30 ADR.
If there isn't an early breakfast bus, take the bus from SSR to the AK and transfer there to a bus to the AK. My advice is to be waiting for th bus at SSR around 8 am./ You might need extra time at the AK to get a bus to the AK. If you get to the AKL early, there is quite a bit to see while you wait.
