We have the Graco Quattro Tour Duo Stroller and have used it the last 18 months. It is a great stroller, durable and plenty of storage space underneath. It folds easy, isn't too heavy (double strollers aren't light by any means though) and it is fairly easy to manuever. It has a cup holder and snack tray for each child and two cup holders for the parents, along with a small zipper pack for keys and cell phone. The innovative handles curve upward so it works well for taller individuals and husbands. It comes with canopies for both the front and the back passenger and they front one is removable. You can put the baby carseat either in the front, with the provided attachment bar or in the rear.
That said, I do have two complaints about it. There isn't a way to "wash" the front seat, the back has a removable, washable cover and the front does not. The second, the front wheels often change to the "non swivel" position on their own if you bump into something.
All in all it was and is a great investment for our two boys, I have a boy who will be 4 in October who still needs to be pushed when we walk for long periods of time and a boy who will be 2 next February. It will work with your Snugride Carseat too so that's an additional bonus.
Congrats on your pregnancy and good luck!
