Up, up and away

I live in a nicely located hotel (nice with regard to the congress centre), which is leaning a bit outwards. On the corridor, the leaning is very obvious and makes it look strange, but in the rooms it can not be noticed. That is my room's door to the right.

Part of the title song's lyrics go "Would you like to ride in my beautiful balloon", and the balloon seen through the window led my thoughts to that.
