Where would you go?

We are FINALLY going to be getting back to our real jobs (our endless furlough ends in November - YAY!), and we'll be traveling to Europe in December for work. Because it doesn't cost much extra to throw an extra leg in and make our flights into multi-destination ones (and just pay for that extra leg ourselves) we are thinking about meeting up with family (we're all spread out around the world) for Christmas.

So... I'm researching places in Europe that aren't particularly expensive (for hotels, etc) that would be nice at Christmastime. Currently I'm leaning towards Prague, but I'm looking for more ideas.

I'm so excited about this possibility and I am really hoping we can make it happen.

Have you ever spent Christmas abroad? Do you have any recommendations or dream destinations to inspire me? Bonus points for cheap hotel recs!
