While the Veer All-Terrain Cruiser Wagon ($599) is technically a wagon, parents have been using it in place of double strollers. It meets stroller safety standards and has all of the same functionality required of a double stroller, but with the option to have fun when you want to use it as a wagon. To make it more stroller-like, just pick up some accessories, like the Infant Car Seat Adaptor or canopy.
