My wife and I bought 24 hour hop on / hop off Eco Hopper tickets, which as the name suggests are valid for 24 hours; and one has unlimited use of their ferries during that time. While that may sound good it is not very beneficial in practice. This is because, depending on the ferry, one can wait up to an hour for one to arrive. That reality, coupled with the fact we wanted to spend time in each place that we landed, meant that we were only able to visit two stops before our tickets expired. We actually gave up waiting for the first of our final two ferries back to Circular Quay from Rose Bay after waiting for the first ferry (from Rose Bay to Manly) for 45 minutes. Instead we took a much faster government ferry directly from Rose Bay to Circular Quay (a route not offered by (Eco Hopper / Manly Fast Ferry) for $7. I suggest saving some money and using the government run ferries, which are far more frequent and much cheaper. read more
