You can be thrown in jail if you do not honor the final judgment. If the kids do not want to go, you still have to take them. I know that is difficult, but it is the law. If it is not working, you may want to talk to an experienced family law attorney to see what can be done about a modification. I would recommend getting more than one opinion, though. Filing a modification without proper legal grounds can lead to unnecessary penalties.

Kids do not get to just choose then change an order. they cannot testify and you need more evidence to change the order.
