Long time since I have used the "parking buses" whatever those are called. How do they work today? I am mainly interested in the route they circulate and the bus stops. I cannot find helpful information at Finavia site, it is difficult to navigate and I only found one statement of airportbus that runs between platforms 21, 10, and parking places.
Thanks for helps.

EDIT: one of the reasons was also to check if it makes sense to use those buses to hop from Hilton to Terminal 1. What is the best = quickest way to get from Hilton to T1?
