We will be staying at the Crowne Plaza Coogee Beach for one night in July. Flying into Sydney at 7pm and leaving the next day from the airport at 3pm. There are 4 of us traveling (2 adults-2 children: 5yrs & 23 months). Better to take a taxi or a bus/train. How long would it take and would would the best rates be? Thanks! --any good cheap restaurants near the hotel you would suggest for breakfast/lunch too? Thanks.
