Do we need a rental car for a relaxed week in Perth with a 16-month-old?

Give Rottnest its own day and check ferry timing, stroller rules and weather before committing. A toddler's nap schedule may be easier with fewer fixed bookings.

Use public transport for compact city and Fremantle days if the accommodation is near a station; rent a car only for outings where it saves substantial time. Compare the cost with parking and a child seat.
