I would like to know which are the best options getting to and from SYD to Circular Quay. Price is a consideration, but not at the expense of riding in a scuzzy vehicle, poor on-time performance, or rude service. For example, in some cities I will take a town car since it's only 10% more than a taxi. It will be 3 adults, 2 small children. Names of companies would help since I'm not from Australia. Thanks.
