There was also a dangerous strainer in the area not too long ago, I'm not sure if it is washed out. That was the year I was going to take that route and passed on it.
Join the Expedition Utah Facebook page and ask/follow river updates about a month or so before you plan to go. Then you can get the intel you need to decide if you want to go or not.
Do the bike ride from fuller bottom camp to the Wedge overlook and back. That's about all I would do with a group of kids. It's roughly 10 miles one way and the road is very easy (good for your support vehicle).
