Does anyone have this Graco Double Stroller or something similar? What do you think of it?

I do not have this stroller, but I like the side-by-sides better. That is what I had with my twins (a Maclaren Twin Traveller). I just thought the side-by-sides were much more light weight and compact. They are also in my opinion so much easy to maneuver, and usually all side-by-sides are made to fit through a standard doorway; I never had any trouble with this, fit through any door and aisle I ever went down. I also liked that both of my girls were the same distance away from me. Also in my decision of getting a side-by-side, I decided that because they were side-by-side there would be no fighting of who got the back/front, no kicking the others seat, and they wouldn't be leaning over the sides or anything to see or whatever. I also liked that they could both lie down, and it would not interfere with who ever was in the back.
