Has any of the rides broke or stop?

Some have, but that is normal for it to happen every once in a while. They are always quick to fix it though.

Every ride breaks occasionally at every theme park around the world. No risk, no reward.

One roller coaster was shut down for a few hours but it was operational the rest of the day.

I was there 3 days ago. All rides were operating all day.

Every now and again but theyre tesyed to make sire the safety of everyone, like Tommy said.

I agree with Tommy.
