My family of two adults and two kids went for 20.00, I believe. My other family members got charged 30.00 for one additional person. You really need to barter with them if you are not satisfied with the price they quote you. It's not set in stone, so to speak!
Anyway, the ride begins just a short walk from the pier...Believe me, THEY will find YOU! There is a long line of buggies just waiting for passengers. Can't miss it! They are across from the line of stores that you see when you first get off the ship.
The ride itself lasts about 15 minutes and goes through a very crowded area of town. I was scared for the horses that a car might hit them! I could barely hear what the driver was saying because of all the traffic noise! It was definately an eye opener as far as what Nassau really looks like (poor!). After the ride, they offer to take a picture of you using your camera.
