We've got a 4x4 Phil & Ted's E3 (?) double buggy, which is great for off-road situations (pretty much all of them out here ), but it's a PITA to travel with unless you collapse it and check it in (in its travel bag and at the desk rather than the gate). Doesn't fold up particularly small, it's heavy to carry (when folded) and cannot be collapsed one-handed. Great if you don't often need to collapse it but the Maclaren is so much easier for travelling.
