We stayed at Chalet Mounier in first week of January, 1 adult and 2 pre-teens. It felt like a safe haven away from the party nightlife of the resort. We loved the bar, it has traditional board games, my two were actively asking to go and play these games rather than play on their devices - it made for a real change and some shared laughter!
We weren’t half board and only ate in the hotel one evening - our last night - one of the boys is a vegetarian, adjustments were made to the set meal to accommodate. Really wish we had ate in there before but I had been put off by some of the other reviews by other vegetarians, all the meals were amazing and both boys wished they could relive the experience all over again. Be aware that if you’re not half board you do need to book the restaurant in advance.
The only thing I would offer as feedback is the Wi-Fi is very unstable - not an issue if you’re on holiday and trying to get away from it all.
