Hello ! I live very near to Switzerland, and I would advise you to go in the Swiss Alpes (or you can come to the French Alpes too, it is less expensive and clearly as beautiful, o even more beautiful).
I advise the The Chedi Andermatt hotel in Andermatt, the town is so charming, the hotel's restaurants are amazing and so is the spa 🙂
I was in Switzerland last year for Christmas it was amazing!
We stayed at the hotel 7132 in Vals, it's beautiful with a unique architecture
