Saving 1000 by staying at Cheyenne vs marvel

I have 4 boys who love marvel but it would be around 1000 more to stay there compared to Cheyenne. The boys do like toy story but marvel is their favourite. Do I save longer to stay at the marvel hotel or just visit it and stay at Cheyenne? Or do I stay in a cheap b&b for 2 or 3 nights and finish up with 1 night at marvel? I want this to be perfect for my boys but I'm not rich!
