Parking can be validated each time we go out. We needed to get the card from the reception counter to use the lift which connects the carpark, lobby, and rooms. Security-wise is good. Convenient-wise, I'd say it 's OK when you get the hang of their system. Probably hotel can give an instruction of how to get from car park to the reception. Maybe I had missed out. We got a room upgrade, so no complaints there. Room was more than our expectation. Thanks again.
