I took my eldest grand daughter to WDW when she was 7y/o and then again when she was 8 y/o. I never even considered a stroller.

She was fine and in fact walked circles around me. I was the one who needed a stroller (hey, just joking).


I had taken her by myself to San Antonio for a week to Fiesta Texas, Sea World, Children's Museum, etc when she was 6 y/o. She didn't need a stroller then either. We ran full speed every day and she did great. If one of us was tired (usually me), we took a five minute ice cream break.

A healthy 7-8 y/o should be able to walk with no problem.
If a kid has a physical handicap where he has trouble walking or has low endurance, then sure, but a healthy 7-8 y/o, no way. lol My youngest grand daughter has Zellweger syndrome (really one of the rare disorders under the Zellweger umbrella). She is blind, mostly deaf and has neurosheath and liver problems. Her therapists are hoping to have her sitting by herself by 2 y/o and maybe walking by 5 y/o. If she does, her gait will be unsteady. However, most kids with her condition don't live past 5 y/o. If she does make it past 5 y/o, she would need a stroller or maybe even a wheel chair in order to do WDW. Of course we would rent one for her, but my other six healthy grand children would be walking at that age. Heck, we took our 3 y/o GS to WDW Feb 4th-11th. We did
rent a stroller for him, but he spent probably 50% of his time walking. By the time he is 5 y/o there is no way he'd need a stroller.
