And I recall there are some "cashless" tolls I might run into along the way. Would that be a hassle/expense to deal with?
Take a taxi or towncar, save yourself the expense and trouble of traffic and parking costs... We once rented a car in Sydney, pretty much found it useless. You could drive to the Blue Mountains, that would be a nice drive, or you could head North, also nice drive, but if you are staying right in the middle of Sydney CBD or surrounds, take public transport, for a 1 day trip much easier.
