I'm assuming Schonbrunn Palace will be even more crowded on a weekend? Can we knock out the palace/zoo/maze in one day if we save it for Monday?
Still planning the itinerary but had considered:
Hofburg Palace and butterfly garden
House of Music
Danube Island and waterpark
I'm sure there are others as well but these appeared to be the most kid-friendly.
The weekend crowds will be unavoidable but any of the above better/worse than others? other places I've missed that are a big hit with kids?
