do take note that for free shuttle going to the airport, it can be very full quickly, and doesn\'t offer luggage compartment. luggage can only be put in the front next to the driver.
Luckily, we kept our luggage at the airport, otherwise our two big luggage couldn't get on the shuttle.
We were at the shuttle stop 10 mins early, there was already a long line up. We barely got on the shuttle.
So for those who plan to shop before your flight, you have to allow more time. Don't wait until the last minute.
