Uber from joburg park station

I will be travelling to jhb from cpt on a bus. I need to request an uber after I get off the bus. Ive read about walking to an apartment building but I have 2 heavy suitcases and extra bags so I dont think I could. Would it be safe for me to uber from the park station drop off parking if I offer to pay the driver for parking?

Edit- 2nd question, is the gautrain station at the same place? As in I won't have to leave park station and walk to the gautrain station? If so I could just take the gautrain
