P ros one seat behind the other means they are narrower than a side by side double stroller. Great for small doorways, crowded areas and those annoying turnstiles at stores. Storing them in cars and closets is also made easier. Cons Because the seats are side by side they are wider than Tandem double strollers making crowded situations, narrow isles and doorways slightly tougher to navigate. The push factor is great but can be a little less than great when you have one heavy child on one side and a light child on the other, although a lot of models now come with a single wheel at the front which help offset this.

The children sit side by side. Many parents like side by side strollers because they feel it is much easier to get their kids in and out of the stroller. Side by sides tend to be lightweight and easy to fold. When folded, side by sides can sometimes be a bit bulkier than tandem strollers. However, many models come with easy pop-off wheels which will make them much more compact so you can still easily fit them in the trunk of your sedan. Many side by side strollers come with larger wheels which makes it easier for traveling on grass or other bumpy surfaces. Also, if you want a jogging stroller a side by side is probably your best bet because you will have many more choices compared to tandem strollers. 2. Tandem Strollers
My only concern is that because the side by side stroller is so wide it will be difficult to maneuver through crowds... However I don't know if this would really be an issue except when trying to leave after the fireworks..?
