It never occurred to me to thank Disney for letting people make their own choices about what is safe for them.
Most people will make what they think is their choice, then if something happens they'll realize they wanted to have a nanny, and they'll sue.
So Disney isn't letting people make their decisions; they just don't have that sort of ride.
Despicable Me is really no more intense then any ride at Disney.
OH I disagree. I've seen kids get jolted and wiggled down way low in their seats. DH saw a woman pop out of her top when it was Jimmy Neutron, because the bouncing was so intense. It's a bouncy ride. All you need to do is ride it on a day when your back is hurting and you'll know how bouncy and wiggy and jolty it is.
For Universal:
https://www.universalorlando.com/park-guide/universal-orlando-riders-guide.pdf. I found this when DS had broken his arm (because he chose to run while wearing new tap shoes on a floor he KNEW was slippery, and no I'm not suing the hotel or the convention center or the convention, despite almost everyone in my life thinking I should get a payout) and we went to Universal with DS in a full arm cast.
This is what they state as a blanket rule. IMO it all makes a lot of sense. I'm glad that the Tuscon lady has had such a great life, but if she had read through this ahead of time she might not have been embarrassed. (I do wonder if she tried Rip Ride Rockit...that one has nothing to do with the upper body once you're locked in) (unlike if she had no lower limbs, in which case she wouldn't BE locked in, like the horrible accident with the Ride of Steel coaster at the Darien Lake Theme Park Resort back in 2011 with the man with no legs on a ride with a lower body restraint)
First, there ARE some rides with one of these as a rule:
Guests should secure or remove prosthetic limbs before
riding to prevent hazards or loss due to ride forces.
OR
Guests must remove prosthetic limbs before riding to
prevent hazards or loss due to ride forces.
Then...
To Ride, You Must Be Able To:
CONTINUOUSLY GRASP WITH
AT LEAST ONE UPPER EXTREMITY.
EXPLANATION: The guest must have at least one upper
extremity or prosthesis exhibiting good grip control with
the ability to brace and strong enough to allow the guest to
maintain the proper riding position through the duration of the
ride, where specified.
INDEPENDENTLY MAINTAIN YOURSELF
IN AN UPRIGHT POSITION WHILE SEATED.
EXPLANATION: The guest must have the body and spinal
control to sit upright without the aid of other people or devices
and be able to maintain the proper riding posture even during
bumping or other characteristic movements of the ride. Certain
units, such as Caro-Seuss-el™ animals, require the ability to
form a saddle posture.
INDEPENDENTLY ABSORB SUDDEN AND DRAMATIC
MOVEMENTS OF THE ATTRACTION WHICH MAY
INCLUDE SPINNING, TURNING, ACCELERATING,
STOPPING, CLIMBING, ETC.
EXPLANATION: The guest must have sufficient awareness of
the nature of the ride and the ability to sit upright and grip,
grasp or hold the restraint mechanism and/or brace with legs,
as needed, during the dynamic motion of the ride without the
aid of other people or devices.
POSSESS SUFFICIENT UPPER BODY STRENGTH TO
INDEPENDENTLY SUPPORT YOUR TORSO, NECK,
AND HEAD DURING THE MOVEMENT OF THE RIDE.
EXPLANATION: The guest must have the sufficient muscle
control to support their head, neck, and upper torso in a
standard, forward-looking position without the aid of other
people or devices during the movement of the ride.
I simply cannot argue with those things. But then I wouldn't take my son on the teacups until he was around 3, when I felt he had enough neck strength (and he was a strong kid, but I'm a former chiropractor and I'm careful with his spine), and I wish everyone would do that. So I can comprehend why they, from their hearts and from their insurance policies, would want people to have all of those abilities.
Of course this means that some rides cannot be ridden by some.
DS was lucky in that the cast just kept him from Hulk and Dragon Challenge. If it had kept him from more, so be it. I didn't want him more hurt, and I wouldn't want him to be in danger of falling out.
WDW does have some restrictions.
