Compared to last year, Avis did not overly recommend insurance this time, but they were very strict with verifying the translated documents and did not provide any additional assistance such as printing services. The staff seemed quite indifferent, as if they didn't care whether you rented a car or not. We had to make three trips before successfully renting a car, though part of that was due to our own issues. Additionally, renting a car on-site without a reservation can be cheaper, but there is no guarantee that cars will be available. We also asked other rental companies nearby; there was a Thai local rental company next to Avis that was much cheaper, but they required notarized documents.
