Anytime Platinum Pass holders do not need to book a car space as the Anytime Platinum capacity is in it's own car park.
Weekday Platinum Pass holders are required to book a car space if the pass holder also has a Weekday Season Pass as this only allows car park access from Monday through to Friday.
Just present your Platinum parking card on arrival. You do not need to use the same vehicle each time as the pass is attached to your profile. You must be present in the vehicle to use your Platinum parking benefit and may be asked for ID on entry to the Platinum car park.
