Can a family fit both Manly and Watsons Bay into two Sydney sightseeing days?

Group The Rocks and bridge walk near a Circular Quay ferry departure, and put Pyrmont or Darling Harbour on the other day. Avoid crossing the city repeatedly.

Manly suits a beach and promenade; Watsons Bay suits harbour views and shorter walks. Check current ferry frequency and the last return before deciding.

Choose one ferry destination as the main half-day outing and leave the other optional. Each trip deserves time ashore rather than a quick return boat.
