The cost is 5,500 per person (buggies seat 2 people with a combined weight under 130Kg but you can take 1 each for the same price). 5 years old and under are free, 11-12 years riding with an adult are half price.
No driving licence is needed as there are no public roads and the entire area is the Tad Kwan Village Park.
