The car rental experience was truly excellent. The Chinese-speaking coffee girl was very helpful and explained everything clearly. She even added me on WeChat and shared local information. The shop is located right in the airport exit hall, and the parking lot at the entrance is very convenient for both pickup and drop-off.
Although Malaysia is right-hand drive and drives on the left, Langkawi's roads are excellent and drivers follow the rules, so even experienced drivers in China shouldn't worry.
