Any suggestions for an itinerary to visit Christmas markets in Munich, Vienna and Salzburg? We’d like to go for 2 weeks, but also include tourist attractions in each city.
Not sure exactly what you are looking for. Where are you flying from? I would fly open and jaw, and I suggest pricing out airfares flying into Munich or Vienna and flying out of Munich or Vienna. You can do this trip by train. I'd put Salzburg in the middle. Rick Steves guidebooks would give you the top attractions in each city and a walking tour for each city. There are possible daytrips from each city, so I'd look at the attractions in each city you are interested in and also if there are daytrips of interest and then assign the number of days you need for each city.
You might have a look at the tour for these 3 cities to give you some ideas.

I used this tour a few years ago in early December to see Christmas markets and enjoy sites in the cities.
