I booked and received e mail confirmation no issues. I was expecting an email or Whatsapp follow up but was surprised when I had an email from Xuan Pha bus saying they would not be able to contact me as I didn't have a Vietnamese phone number. They asked for me to send a photo of my wife and I, which I did, but I was a little concerned. The email also asked that we be at the pick up point 30 minutes before departure. We arrived 30 mins beforehand and before we could locate the bus the driver found us which worked really well. The bus and seating were clean and very comfortable and the driver was really good. I will have no issues booking with Xuan Pha again.
