There is a counter in the airport hall which is very convenient, and the procedures are quick. When returning the car, you can't enter through the exit door; the security personnel will guide you to a small pathway for the return process. During the vehicle inspection, all visible minor damages are noted, and during the return, the staff just does a quick check. I offered a tip when picking up the car, but the staff politely refused. Due to the narrow lanes in the parking lot and my lack of experience with right-hand driving, I requested the staff to move the car to a wider road, and they were very helpful. I initially booked a TOYOTA VIOS but later found out it had been upgraded to a Toyota Altis, which was fairly new though previously a bit damaged. We chose Toyota because it was pricier, but we had a lot of luggage. If the luggage amount is known, a smaller car like a Nissan could work. I was very satisfied with Thai Rent A Car, even booking another car with them in Chiang Mai during our Phuket trip. I will choose this company again on future trips to Thailand.
