四月分将来澳州出差，顺便在悉尼停留两天。目前已订好机票和旅馆（在市区中心附近）。
行程是：
DAY 1（星期六）： 上午10：00飞抵悉尼机场（澳州国内航线）
DAY 2（星期天）： 全天在悉尼
DAY 3（星期一）： 下午2：40国际航班离开悉尼。
初步计划（寻求建议）：
DAY 1：下午乘轮渡到Manly,欣赏海边风景 and take a scenic walk along the shoreline，傍晚乘轮渡返回Circular Quay
DAY 2：OPTIONS ARE
A. Take a Blue Moutain Day Tour (any good tour operator to recommend?);
B. Visit Taronga Zoo (1/2 day) and spend afternoon near Circular Quay (for Opera House or Royal Botonic Garden) or near Darling Harbour (for Sydney Aquarium or just walk around and do some shopping for sovenior);
C. any other places within walking distance from CBD are recommended?
DAY 3：??? before heading to the airport for flight - I will have the whole morning free for additional activities.
第一次来澳州和悉尼，any feedback and suggestions will be helpful and appreciated.
