I spent yesterday pushing my hefty (44 lb, 43 inch) 4.5 year old around Hershey Park in my trusty old Maclaren Quest and it was far from the easy glide I remember from her younger, lighter days. I'm wondering now if I might be better off renting a City Mini GT for our upcoming Disney trip. Are they really easier to push around than my Maclaren is? Or is it just going to be hard because she is heavy. I'd hate to spend the money rent the stroller only to find out it's just as hard to push her around anyways. Who out there has rented the GT or the regular mini for a bigger kid? Tell me about it!
