It's not often I agree with Rebecca, but I think the double buggy is a great idea. I seriously doubt that Alfie will be in the buggy for the most part when they're walking between Las Americas and Los Cristianos (or wherever they choose to walk to) he's an active, full of energy 5 year old but at least having the double buggy means there is an option for him to climb in when he gets tired and it isn't hindering what they want to do.
