I am going to be visiting Europe in either September or October and will have small kids so I want to have a one day stopover somewhere.
I am somewhat flexible where we first land in Europe, but either London or Barcelona would be ideal. I have found that adding stopovers can dramatically increase the price. For example, changing a one way flight from MEL->BCN on Singapore airlines doubles in price when change it to 2 separate flights with 1 night in between.
Any advice here would be fantastic.
how small?
