Since DD has now outgrown our MacClaren Major stroller we planned on buying a Convaid Metro 16". They are $950. DD doesn't necessarily need it for mobility although she doesn't have the stamina to walk 7 or 8 miles a day in WDW. We use it more for eloping issues in very crowded areas, to help with waiting in line and to give her a defined space when she becomes overwhelmed in crowded & loud situations. Now I am second guessing my decision and wondering if we should simply purchase a transport wheelchair which is in the $125-$150 range. Any thoughts? We do encourage her to walk as much as possible but there are times when it just isn't safe or we need to keep her from entering others' personal space.... We do not use it when simply going to the grocery store, Target....but will use it at the baseball stadium, zoo, WDW and other less frequently visited places.
