Children School (Haiti)

Dear All,
In a few days time my wife will be travelling to Haiti to work with MINUSTAH in Port-Au-Prince. We are also planning to move our five years old daughter to stay with her mother. We would therefore be very grateful if you could kindly advice us on the availablity of children school in PAP. From the information i so far obtained from the Internet the Union School meets our requirements but, we are worried about transportation and traffic. Is there any other schools in PAP main - or - safer and quicker transportation service for kids? Please advise
