I'm coming in late to this party, but have to join with others in stating that camping in the park itself is completely safe for families. We've spent MANY nights there and have no complaints other than the rising fees for the campsites. For the cost of the sites I'm more than willing to travel elsewhere for camping of equal quality.
The comments about laser show are correct, though. If you plan to stay for it, you may want to camp in the park that night. It takes FOREVER to get out unless you leave before the end of the show, it's already late by that time and it's no fun to travel elsewhere to a campsite that late.
Best of luck to you.
