We rented a stroller for a week for my daughter back in 2010 and she was 7 1/2 !!!! It was a double City Mini jogging stroller for her and my 4 yo son. They used it when they needed it! It was always there for them. It was VERY useful at the end of the night, heading toward the monorails to get back to the hotel. I wasn't carrying heavy sleeping kids. It was a god-send. I highly recommend Orlando Stroller Rental. They are fabulous. They delivered the stroller right to our hotel and they picked it up from there too. The stroller they provide is super easy to fold and carry. It was really fantastic. The stroller was very clean and we had MANY people ask us about them in the parks. Don't hesitate to rent a stroller. If you have it, you will definitely use it!
