Good experience overall, but I booked with full insurance, yet they said I only had basic insurance when picking up the car. Quite confusing.

Always use Avis when vacationing in Phuket. International brand, trustworthy!

The car pickup process was simple, but I couldn't find the return address.

The car had various scratches when picked up. Despite returning the car with a full tank, they charged an extra 300b.

Like: Avis counter is located directly outside the baggage claim (if you land in the main terminal). The process was quick and the car was already parked outside ready for us.
Dislike: When leaving, we were going through the other terminal and there were no visible signs about where to return the car. I drove around the airport 3 times until someone directed me to the parking lot. Even after driving into the parking lot, it was difficult to spot the Avis signs and teams. Once I got there, I had to return the car and then return the forms to the counter inside the terminal (which was time consuming and inconvenient). There should be ONE place to return the car and forms, or someone should have done this for me.
