I am trying to decide on a side-by-side or a front-back stroller for my 4yo and 2.5yo for our next trip. I am worried that it will be hard to move through the crowd with a side-by-side stroller. Does anyone have any experience with this that could help me out? Is there a favorite side-by-side brand out there? I have been looking at the Graco Duo Lite. Thanks for any help!
