Has anyone used the kids eat free cards? For £10 per child you get a card which entitles the child to eat free as long as there is full paying adult. It covers a big area and participating restaurants include Ponderosa, Sizzlers Restaurant, CiCi’s Pizza, Cattleman’s Steakhouse, McDonalds Bistro, NASCAR Sports Grille, the Butcher Shop Steakhouse, Basking Robbins, Pacino’s Italian Restaurant, Passage to India Restaurant and many more. Of course they can't be used in the parks. What do you think guys is it worth it? Has anyone tried it and had problems?
