There are a lot of appealing things to mention about this resort in Grapevine, but as far as your kids are concerned they only need to hear a few: indoor water park. The splashy facilities housed in The Great Wolf Lodge are actually the largest of their kind in the U.S. The resort also features themed rooms and restaurants, an activity center and arcade geared towards the little ones, and a fitness center and top-of-the-line spa for the grown-ups to unwind in. Add to that a healthy dose of rustic charm and you have one enticing summer destination. Pack the bags, Papa Bear.
