Double buggy best for travelling?

[justanothermanicmonday1]

Will have a 1 year old and a 2 year old travelling to Portugal at the end of August.

Does anyone have a double buggy they recommend?

Thank you!

We have a mountain buggy nano duo. Which folds fairly flat (I think it's the smallest fold double stroller) its also really light and can be carroed with the shoulder strap. We brought it for our holiday last year for our 11 month old twins as didn't want to take our bugaboo donkey. It's now the main pushchair we use.

Do you need double or will two singles be better? We opted for two singles so that we could each take one and then used the carrier on the one occasion that I needed to be with both on my own.
