1. Hotel pick-up and drop-off, half-cartridge pickup and drop-off, slightly different from airport pick-up.
2. Working hours are 8 am to 5 pm.
3. Kudos to Ctrip's 24-hour customer service: Originally planned as a half-hour drive to return the car before 5 pm, but due to temporary traffic congestion on Highway 101, making it impossible to arrive before 5 pm, Ctrip negotiated with the car rental company multiple times to return the car at 8 am the next day without extra fees. In my excitement, I filled up the car rental company's tank with 3/4 of the gas! 😁
