When did you stop using stroller? Ours is broken and debating whether we still need new one?

20 month old twin boys ~30lbs each. We currently have a Uppababy Vista v2 (incredibly hard to push around at this age with weight distribution) and a double (side by side) umbrella stroller that is now broken.

We're debating whether to purchase a new double stroller (side by side), or just get a ride board for the Vista.

When did everyone stop using a stroller? Would it be worth it at this point to get another side by side stroller, or just tough it out for a bit if the boys aren't going need a stroller much longer anyway? Should we consider a wagon?

Currently live in pretty walkable area that requires some sort of stroller for safety, especially when one parent has both boys at the same time. Width/size is pretty important as there's a lot of old buildings with narrow doors.
