I found Phuket Luxury Transfers via Google, as was being quoted expensive pricing from the hotel.
It was such an easy and very efficient process to book the car of your choice and at a great price (credit card facility too).
We opted for the Ford Explorer, which was plenty big enough for the 2 of us and our luggage — travelling in a 4WD as you see more.
We were greeted at the airport and the car arrived shortly after, no waiting and free wifi/water and cold refreshing towels too!
Booked them for my pickup also on the way to the hotel.
You won't be disappointed.
