15 year old daughter and I assume Annie you are a young mother. I would recommend you rent a car. The area you chose is not the best maybe Maho would have been better for your trip. I have a villa in Tamarind Hill near Oyster Pond.
It is very quiet and not great for a 15 year old. Oyster Pond has a pizza place and a few restaurants and that is it.
Sorry to not be of much help but the area you are staying at I am not very familiar with. Good Luck.
