Hello! I was hoping to visit Vienna during Christmas Day and New Years. However I wanted to confirm if any of my bucket list sites, Schonbrunn Palace, Hofburg Palace, Belvedere Palace, and Kunsthistorisches Museum would be open during Christmas Eve, Christmas Day, New Years Eve, and New Years Day. If you can comment on the availability of public transport and cafes during these times, I would appreciate it as well.
Thank you!! Happy travels!
