Opinions needed for visitation...?

You need to go back to court and have dates set, letting him choose when to have her gives him all control, and since it is his choice there is not much you can do. But if you let her go to camp and tell him, sorry she will have to come when she gets back, he would actually have to take you to court, which would take a while, and since this is doented with your lawyer and you can prove that you made the plans for her trip to camp before he sent you his plans, then you should be fine. Especially if your daughter speaks to the judge and says that this is what she wanted to do. He sounds like a piece of work, my ex does the same stuff, he is supposed to have them every other weekend, maybe once a month he takes them. Good luck
