These days, one needs one’s own private nightclub – the USP of the latest luxury chalet opening in Courchevel 1850. Chalet Edelweiss, agented by new specialist Summit Retreats (www.summitretreats.com), has its own pool, library, gym, spa and nightclub – with a capacity for more than 100. The slope-side chalet, sleeping 16, costs from a soaring €100,000 a week.
