Visited Salzburg over Christmas weekend of 2008. We were looking for a place with a good holiday feel to it. Salzburg delivered. A culinary must while there- white hot chocolate. Visit the Festung and walk along the hilltop for some great views of the surrounding area.
Place to stay- Ramada. Sounds bad but it is fairly new and very trendy. Much nicer than the ones you might know in the USA.
