Anybody knows how long it would take to drive from Hanga Roa, along east coast to Ahu Tongariki. Then going north to Ahu Nau Nau and back to Hanga Roa through road along the middle of the island. Can it be done in one day with short stops ? Could I have time to cover the western side of the island to Ahu Tepeu ? Are there any wash room facilities and restaurants along those roads ? Thanks.
