If you are booked into the CPS car park, you just drive up to the terminal as directed - have your sticker on the windscreen. Your luggage is taken out and you hand your keys over and get a receipt. You then just walk into the terminal and your car is taken away and parked. On return, you collect your luggage from the baggage hall, put it on a trolley and walk across the road to the car park. You hand in your receipt at the hut and they give you the keys and tell you where it is parked. All vey well organised.
No the car park is very near to the ship. We booked in advance and after unloading our luggage the car was driven away to be parked for the duration of our trip. A wonderful service, hassle free.
You just get out of your car next to the ship. Unload your car. Then the car is driven away and parked for you. The car will be returned to you when the ship docks again! Happy cruising.
