Hey, I have a solo trip flying into Budapest and out of Vienna. I would appreciate any comments and advice!

This will happen in September. The plan would be to follow things in approximately in this order and then bump things to the next day if I run out of time.

I know I won't have time for most of the museums, so was thinking to mainly check out the architecture. Are there any must see museums I should enter? I may get a city pass (need to see what it covers).
