With our latest trip in January, we had a hard rule that if we weren't in line and we weren't on a ride or restaurant, then they were in the stroller. They knew we'd be having long days and this ensured those little bodies weren't having a meltdown at 2pm. Our 3 year old fell asleep in the stroller at one point for about 45 minutes, but after the first day my 5 year old quickly understood why we wanted her in the stroller. As a mom, I liked that I wasn't chasing kids down Main Street. Nobody in our party minded having a stroller to tend to.
