I asked & received a recommendation for a taxi on here as I had no means of getting my luggage to Jomtien except another taxi. I used an all-female company called Nam/Nam. They were terrific; 1000 baht for small car; emails in good English/driver identity/contact number in advance. Collection from BKK similarly trouble free.
BKK was a doddle compared to the sh1thole of Manchester. Coming back I went to a Priority lane 'cos I was old & got excellent treatment.
