My Husband and I will do part of our honeymoon in Europe where we land in Vienna on December 15 in the late afternoon and depart from Prague on December 21 in the early evening. Would it be too much to do Vienna - Saltzburg (1 night) - then to Prague? We haven't been to either of these countries before. We're definitely into visiting the Christmas markets, the main castle/palace sites, an opera in Vienna, and maybe a city walking tour in each location. We don't want to do a bunch of museums on this trip, or feel the need to see every neighborhood. I do feel like we'll be a bit constrained with the limited hours of daylight for certain activities.
I've heard good things about visiting Saltzburg, and wonder if it might be worth it to fit in with this timeline if we're sticking to the main highlights in Vienna and Prague? We could take the trains, but I've also seen all day private guided trips from Vienna to Saltzburg (and maybe Hallstatt). Then we could take a train the next day directly from Vienna to Prague rather than Saltzburg to Prague.
Appreciate any feedback or personal experiences!
