Vienna was chosen by a usual plan of looking at the price of flights in the October half term and finding something reasonable. Once flights were looking good, we checked out Airbnb filtered by Superhosts and those with a decent number of 4.5+ reviews. We lucked out on our Airbnb, it was excellent.
It felt like we did less planning for Vienna. It’s a big place with tons of stuff to do. Looking through our go-to Lonely Planet felt kind of pointless; too much to do in not enough time. The ’72 hours in Vienna’ tips are kind of helpful, but we’ve learnt over time to make trips like this an 80/20 split in favour of the kids. And we know they’ll be happy with a constant supply of food and playgrounds.
