Not crazy at all, my 6 1/2 yr old is 35lbs, maybe 41 inches. My friends just turned 2 yr old is almost her height and weighs more than her. As moms we know our kids limitations. I take turns between putting her and my 1 yr old in the stroller. Ds was 2 1/2 on his first trip to dland and I never used a stroller for him. Each child is an individual so if they need a break why not give them one. Besides if you end up not needing the stroller its great for carrying all your personal belongings.
You take it back to your room unlike the in-park rentals. You carry tons of stuff in it. I'll be sad when I can't have a stroller at DLR anymore!
