Renting a private air-conditioned mini-van, complete with English-speaking driver, is a great way to go where you want when you want. You will be picked up from your hotel and then you are free to experience Phuket according to what interests you and you only.

There are so many sites to see in Phuket, and the easiest way to experience them is to hire a personal guide/driver. 

There are countless attractions and activities in Phuket - the beaches to the lookout points to the temples to the golf courses to the shopping malls to the theme parks to the spas and much more. In fact, any daytime attraction in Phuket is within reach using your own transportation for a duration of either 4 hours OR 8 hours.   

And to keep it simple, it is one price whether it be for 1 passenger to 8 passengers.
