Edge of the world with baby

Hello Bonjour Saudi

My parents are visiting and we hope to go to the edge of the world in November. It would be 4 adults and we have a 2 month old baby.
Is it possible to have a car for all of us? We can bring our baby seat? It also means We may need to stop to feed her on the way or way back (she eats quickly). If it’s a private tour is this ok?

Thankyou and look forward to hearing from you,
Emma M.
