How old to ride without a parent

[tobin04]

In Disney my 14 year old can ride with her younger siblings without a parent. Or maybe I should say-my littles (ages 5 and 9) can ride rides with my 14 year old without us. Same for Universal? What are the rules?

"Any child who meets the minimum height requirement of the attraction but does not meet the 48" (122cm) ride-alone height requirement must be accompanied by a Supervising Companion. A Supervising Companion is defined as someone who is 14 years of age or older and meets all other attraction ridership requirements. Children under 48" (122cm) must be able to sit upright unassisted on all rides, with the exception of riding The Hogwarts™ Express and the Caro-Seuss-el™."
This is what I found

Touring Plans also confirms this. A child must be 48 inches to ride alone OR have someone who is 14 or older with them.

To put it another way, if you’re 48” AND meet the height req of the ride, you can ride alone.
