We'll be driving from Melbourne to Sydney next week for a holiday. We need a reasonable and secure car park in the city (or maybe outskirts) as we're staying for 6 nights. We probably won't use the car for the 6 days as the hotel (Meriton Kent St) is in the city centre and we'll be travelling by foot or public transport. Is 815 George St, Haymarket (Wilson Parking) secure? They charge $15 flat rate for the whole day. How about Citigate Central Sydney which charges $22/day? Would really appreciate your advice.
