The best way of experiencing Vienna's Imperial Palace, Hofburg, is by joining a ball there. My friend Elisabeth and I went to Kaffeesiederball because it is one of the most popular, takes place at Hofburg and is a great place for us to meet local friends and acquaintances.
Most of the time we just went exploring the different dance floors, did people watching and had a chat with friends. The dance floors were super full - it was almost impossible to dance but big fun watching the crowds.
At 2 a.m. we managed to get some seats to rest. If you just have a flaneur ticket, you are not entitled to a seat but have to watch out for an opportunity. All in all a great experience.
