Let each daughter choose one activity and keep time for a neighbourhood wander.

Ask whether after-hours return is allowed and when responsibility for the car ends.

Compare ferry or flight arrangements, time actually on the island and the walks included.

Look at current menus for casual Asian eateries, takeaway counters and food halls around where you will already be sightseeing.

Try one ready-to-eat item and leave room for produce or a snack to take away. Compare menus and prices on the spot rather than following a fixed stall list.

Choose one dinner booking as the fixed point, then add a nearby bar or laneway walk. That avoids spending the celebration crossing the city.

Map the walk to your plans and check recent reviews for lifts, noise and maintenance. Southbank buildings differ even when they are on the same street.

If you can spare a night, an overnight trip is much less rushed than either day option. Check weather and road alerts close to departure.
