You are not permitted to leave the Kingdom of Thailand. Failure to comply with this requirement will void all insurance coverage. Please note no international one ways are allowed. Vehicle can be taken on a ferry to the Islands in Thailand.
I tried to book a Nissan X Trail with National Car Rental at Chiang Rai Airport, but they say they have no vehicles available for the dates we want. But you seem to have that car available with National for those dates. How is this possible?
They are reserved for bookings through our site....if you need the car and you see availability I would book it quickly as it is very busy in Thailand now.
