As a Plat. you will def. get access to the lounge. Just be sure to ask for it if its not offered. The lounge is pretty nice with a wide selection of drinks and food. Also the staff are great at this hotel. I think there is a car service to the airport. My trick though is when you exit customs you just tell those pesky drivers to F. Off

Then take the elevator upstairs and wait for a taxi up there. All the licensed, metered ones drop off passengers there and can also take you to the city. Hope you have a great stay.
