Storybook Island is a wonderful place to take your kids for the day. You will find all of their old favorites such as Barney, a bunch of the Disney characters, The Wizard of Oz, Santa, etc. There is also great playgrounds. If you go in the summer, they offer a free play on certain days. We just went, and it is very entertaining for the kids, and a nice break from running around.
Be sure to check it out.
