Does anyone have any experience with the city mini stroller offered by Orlando Stroller Rentals and Magic Strollers for older children? My children are 6 and 5, and average size for their age. I would have preferred the classic offered by OSR, but they are sold out. Is the city mini manageable with children with a combined weight of close to 100 lbs? I wonder if my 6-year old DD will even be comfortable in it. Clearly, they will be walking a lot, but we want a stroller for those long days. Thank you.
