I know a lot of kids act like heathens on vacation (ok, sorry, most heathens I know have a lot of respect for others) and the parents like to believe that being on vacation means they get a break from parenting also...but it also is very possible for the most well behaved, very properly raised kid with very attentive parents to make a momentary snap impulsive action...and I really don't think anyone on here thinks parents must stare constantly at their kid while on a ride, never looking at any of the ride themselves, just in case they suddenly reach for the water. Doesn't matter how many times you are told to keep your arms in the boat, kids don't always follow the rules...and if you think yours do, please let me know your secret (or your drug of choice that gives you that hallucination).
Could have been a split second dumb choice, like kids make everyday, good kids and bad. It is true their brains aren't developed yet, DW hates when told by a child therapist (DD had some bullying issues) that we can't expect every choice to be logical in a 13 year old. No matter how smart she seems to be.
If true, I feel sorry that they will have to deal with this for the rest of their life, and that it ruined a great family vacation.
Oddly when I look at the ride times on my iPhone it says it is open, but them almost half the other rides say closed, so might just be my app being buggy.
