Hey Luis,
I am sure if you go down to Flon, or by Place du Tunnel, or to some smaller places around Bessieres you will find some party-action. :O) I've already seen some things planned at Bleu Lezard, for example. I think Le Bourg is open too.
Me, I am going to Berlin to visit friends: just as cold, but way more going on! And it is crazy. Two New Years ago, I was at a party there: a flat just to the side of us caught on fire as there were SO MANY fireworks being set off by people on the street, on their roofs. Total exhilirating chaos.
And the night train is only 184.- round trip.
Hugs and good luck!
Jacki
