If you have kids who use internetm then think about taking a portable computer that has a satellite uplink capabilitym then you will be able to travel more freely without your offspring saying "I just HAVE to use the computer"
Bring lots of warm clothes. Being that everything to do was outside I was definately glad I had brought lots of layers and waterproof clothes. It was windy and cold at the top of the mountains- definately had to stop and get some gleu wine (don't know if it is spelled right, but it is called glow wine and it is warm and delicious.) If you are ever in Germany, Austria or Switzerland you have to try it. But don't drink too much... Gets you drunk fast and that doesn't go over well when you're skiing.
