I have kids 16 months apart. Our 1st double was a Graco DuoGlider. It maneuvered well, but it was a tank. The rear seat reclined flat, though, so it was good for a newborn. Once the younger one was sitting up, tough, he didn't like the back seat.
Our favorite WDW double, though, was the Combi Twin Sport. It's a side by side, but it was very lightweight, maneuvered well, wasn't terribly wide, and folded decently compactly for a double. It doesn't have full recline, though. It does recline fairly far back, just not flat. It does have a compatible infant carrier/car seat.
