I didn't take the airport limo in March, but a regular taxi was easy enough. The separate destination lines are well marked (and the taxis color coded!). There was also a "helper" to give drivers the hotel names in Chinese. Taxi was about $50 each way.
The lounge offers a -moderately- obstructed view of the harbor and an excellent breakfast and hors d'oeuvre selection. I was comped to exec level with Marr Gold.
Enjoy your visit.
