Christmas at self catering hut in the Bavarian Alps

Hello all together, since I do not want to celebrate Christmas with my family, I go from 23.12.19 to 26.12.19 on our section hut of the DAV. The hut is located in the mountains around the tranquil Lenggries. It is a self-catering hut, which means that food must be brought up and cooked there yourself. In good weather you need about 2h and in snow 3h to walk up. Above can then be enjoyed in peace and quiet life! Small walks, eat drink, play games! All these things in absolute peace and seclusion! A public hut is 10 minutes away but I can not say for sure when this is open over Christmas! Non-alcoholic drinks and beer/wine are available upstairs enough. The cost is 15€ per adult and 10€ per student for one night each. Beer 1.80€ Spezi/limo 1.50€ Water 1€ These are the costs in addition to the food. Additional costs are to be expected! Of course you can also stay only 1-2 nights and then go home again, but for simplicity's sake I would like to run up closed with all together on Saturday. Food we / I buy in the valley and then have to carry them either with up or can drive them up before in good weather. There are two bed camps, once with 8 sleeping places and once with 4. Duvets are available, but a hut sleeping bag or sleeping bag should be taken. Questions I answer with pleasure and also take suggestions in the planning!
