Thanks to Kacee, seawolf, lafemme, AirbusFan2B, and Tokyoite for all of your advice on chauffeur services/airport transportation!
I am familiar with Hong Kong and the airport express train, but I'll be arriving around 10:30PM, so by the time I reach HK central station the complimentary hotel shuttles will no longer be running. Hence, why I was looking at chauffeur options.
However, upon second thought, I think I'll take the express and then taxi/uber from the station to the hotel since it'll only take a few minutes longer and I'll save $100+ USD.
