I reserved for a small SUV rav4 and i got a free upgrade To a bmw x3. Wow! From the airport, you have to ride the skytrain to car rental station which will take 15 minutes walk and travel via train. Registering and getting the car is hassle free. They have an option to return the car with tank full, please always select that. Upon returning the car, drive To car rental area again, dont drive direct to airport. Returning the car is again hassle free, as ive been welcomed by staff.
