Do you need a phone to call over to them on the Lagoonarium? We are renting a car and driving there but need to be back to catch the Ferry back to Papeete at 5pm. We are hoping to get to the Lagoonarium by 10am and spend around three hours there. Can anyone suggest what we could do in the remaining 3 hours we have the rental car? How long would it take to drive around the island? Also which side of the road do we drive on?
