I am looking for advice on a stroller that can handle a lot of weight. My DS is 6 and 48" and over 60 lbs. DD is 2 and about 32lbs. At home he walks, and she rides in our single stroller, But I know he will get tired and want to ride at WDW. We rented a double stroller last time, and they both fit, but I wasd hoping to buy one, and save all the rental fees. Does anyone have any suggestions? Perhaps I am dreaming but is there any lightweight or umbrella stroller that could hold a combined weight of 80+ lbs?
