How should four adults pace nine Perth nights with Fremantle, Rottnest and a northern road trip?

Confirm late arrival food options, current transit fares and road conditions close to travel. Leave a spare day so weather does not force every stop into one drive.

Break the northern drive into realistic daylight legs and book the overnight stop before planning sunset viewing. Do not base the budget on an old claim about the cheapest fuel day.

Group the car-free Perth, Fremantle and Rottnest days together, then collect the rental only when the road section starts. Check ferry bookings and the actual transfer route for each day.
