Hi there, while I agree with others that the ride is safe, I wanted to share my personal experience/feelings the first time on took my very tall skinny 5 year old on. Who had been tall enough since 4 to ride but we told him no!
First off, let me say he loved it and can’t wait to go back on.
For me, I was a little less thrilled given the seats at WDW are stacked front to back and not side by side. Couple that with the fact your in pretty much pitch dark and can’t see or touch him. When we arrived back at the station he was very happy, but also pretty slouched down in his seat. Again at no point did I feel it was unsafe, just all around uncomfortable for me as a mom then I even be able to see/feel he’s with me and ok.
He wants to ride the pitch black version at
MNSSHP next week but I’m going to pass on that one.
When he’s got a little more muscle and bulk to him I might feel better that he can keep him self a little more upright and in a proper position. Again not really worried about something crazy happening, just more so worried about a pulled neck or bumps and bruises from slouching around.
Just my personal take on the question. You know your child and yourself best!
Hope that helps
