You can only book reservations in selected car parks. You will be asked to select the entry and exit time and pay in full for your parking.
Booking/paying in advance for your parking session allows you to enter and exit the car park as many times as you need to.
Please note: As this is a new feature, the reservation will not appear in the RingGo app, so please do not be alarmed. You just need to ensure the vehicle registration number in the confirmation email is the same one you are parking on the day!
