Once you’ve exhausted yourself shopping and dining, it’s wise to keep in mind the various relaxation areas within the Hong Kong International Airport.
The Travellers Lounge is one example of this: for a single entry fee, passengers can partake in all day food and beverages, showers, internet, nespapers, magazines, and international TV channels.For the more extravagant, there is the Plaza Premium lounge, with some added extras: massage chairs, music, and in-house movies amongst those.
However, it’s in the Plaza Shower and Relaxation Lounge, located near Gate 60 in the West Hall, that a weary traveller finds his heaven – 8 shower stations, and 9 semi private nap rooms are open 24 hours.

Luxury such as this obviously comes at a cost however; depending upon which “package” you choose.
The Plaza Premium Lounge website covers all their services and package prices.

Also, you can always try out some of the massage booths at the Hong Kong International Airport. In particular, you might want to visit the “Oriental Healing Art” facility at Gate 40, for a relaxing foot massage.
