I LOVE Wien, music and Gustav Klimt.I will tell you way to enjoy for your trip.
It's an one and a half day Recommended tour.I went to the opera show named "La Bohème" at the WienerStaatsoper at that night.I want to get there again.

Santa Claus Village is very beautiful scenery and I got excited. The first impression was a blue and white snowy landscape. but I found many christmas goods of red , green and gold in the store, Instantly. All the stores were in full Christmas mode- it's warm color or light.
Please try to go there to because it is a very romantic place.

I went to the Icehotel four years ago.
It was a great place!
Church made ​​of ice was beautiful.
