big buddha and worry about the car journey

plan to go big buddha Ngong Ping.. go by cable car, n back by bus. I'm afraid with curve road and also carsick. How the journey? If we take the the bus down, there's nice view along the journey?we need to confirm single trip or return trip of cable car before getting up? If we buy a single trip, could we add on to return trip at Ngong Ping there? The vege restaurant operating from what time?tq..
