I was told to go for the Christmas markets but am unsure what other highlights to do in just 2 days. I've been to Austria before a few times, but never Vienna.

1) Visit the Opera (try to get a ticket for a play). 2) Walk and apppreciatte the architecture and relax in gardens. 3) Try cakes and a "menange" (capuccino). 4) Visit Prunkraal, the barroque library: not everywhere there is a place like this. 5) Schonbrunn Palace: it may take you a whole day, but at least go there and do a quick visit. It's a must in Vienna. Enjoy Vienna! about 8 years ago
