So I just broke down both options to myself am I'm gonna try and put them down here, someone correct me if I'm wrong.
All amount of money and time are aprox.
Option 1 - You use DME, you don't have to get your own luggage but at worst, you make it to AKL in 2 hours from the time you step off the plane. You go to the little store at AKL and buy some things for the week, lets say you buy 20 items and compared to the local grocery store, you spend $1-$2 more on each item. So lets say you spend $65. ($30 more then the grocery store, Publix).
Option 2 - You hire a car service for $70. You have to get your own luggage and find the car, this takes 20min. They drive you to Publix where you buy the same 20 items for cheaper and it cost you $35 total, this takes 30 min. You leave and you're on your way. It takes aprox 30 min total driving time to get to AKL so your total trip is 1 hour and 20 min. You saved $30 at the store and got to the resort 40min quicker BUT you still spend $40 more because of the fee for the private car.
So, the question is, are you willing to pay $1 per min to get to the resort quicker then the DME?
