We are from Indonesia and travelled in a big group of 10 (which included 5 children). We used VBT to take us from Don Mueang Airport to a hostel near Lumphini, then from Bangkok to Pattaya and back. Overall, we had a satisfying experience. The van is spacious and comfortable to fit us all in. The drivers were friendly. The admin was quick, responsive and communicative. The rate was also reasonable. I highly recommend VBT for point-to-point pick-up van service especially if you are travelling in large group in Thailand so you can avoid all the hassle of taking train or bus.
