Ever. Don’t even think about it. And don’t get with anyone in the chalet for that matter. It will only will result in any subsequent communal chalet time being turned into a rendition of Snow Sex and Suspicious Parents as you try awkwardly to avoid eye contact at the breakfast table.
If the desire to copulate is really too overwhelming for you to contain, there’s always the télécabine or the jacuzzi – the chalet host’s shagging spot of choice. But do bare in mind, you won’t be the first (or the last) to fornicate in the bubbling hot tub. So just be wary of any floating rubber protective ‘gear’.
