In Vienna and Salzburg - around New Year's day

Hi,
Some friends and I plan to be in Vienna and Salzburg for the last week of Dec and first week of Jan Protected content .
We appreciate some tips for places to visit, especially in Salzburg during New Years day.
Also, we welcome any locals that have the time to show us the beautiful country of Austria.
Please feel free to email me.
Cheers,
Lili
