If you and your travelling companions can't secure that perfect hotel in Tuen Mun itself, then you should consider securing accommodations in Discovery Bay or Mui Wo. The Silvermine Beach Resort in Mui Wo and the Auberge Discovery Bay Hong Kong in Discovery Bay are both worthwhile alternatives.
When you are ready to stop working and start adventuring, Wotif will help you out, from accommodations to activities.
Hotels in Tuen Mun start at AU$126 per night. Prices and availability subject to change. Additional terms may apply.
