My girlfriend and I are traveling to Vienna for four nights in December 2020. We will be using one of those days for a day trip to Bratislava. The other three days, we will be exploring Vienna and enjoying the Christmas markets.
We will have 4 more nights to spend in Europe before heading back to the US. We have considered Munich, but were curious as to which cities would be best for 4 nights, which are a train ride away from Vienna. We are interested in history, culture, and of course the Christmas markets.
