So, given that, it would seem to make sense to book for earliest entry and latest departure, rather than your estimated times, as it costs no more to do so?
I got the impression from the Wilson booking website that you have to book the number of different part or full days you will be in a carpark, rather than elapsed time.
ie if you booked for entry at 2pm Sat and departed the next day at 1pm that would count as 2 days parking, not 1. Even though you only parked for 23 hours. Can anyone confirm this?
I think Australian prices include the gratuities. On the downside I think the price is AU$92 EACH as the discount already reflects 50% discount for second person. "BUY ONE, GET ONE 50% OFF (PRICE REFLECTS DISCOUNT)"
