Things to do in Laguna Beach for family with two boys, 10 and 12?

All of the above sound good. Newport Dunes is close by, try that, they have paddle boats. Fishing too. You can find day trips (boats). You could go to Catalina for a day or two. Disneyland is close by. Angels Baseball is in Anaheim. Pirates of the Carribean is in Buena Park. Get a Tour Book from the Auto club.
