I love that area, I wish we had the money to take a trip there ourselves this year. :D
There is a great little place right down the road from Storyland called A Better Life Cabins and Campgrounds. You can rent a little cabin with two bedrooms (one for you and one for the kids). The cabins are different sizes and book pretty quickly, so if you want a two bedroom and a kitchen, get right on the website and book early. The bathrooms are tiny, but you can't beat the price (rent a whole cabin for less than the price of most hotel rooms), and the owners are lovely people. It's been a few years since my husband and I were there last, but we have fond memories.
Here's the website: http://www.abetterlifecabinsandcampground.com/
Hope that helps! Have fun!
