A.S.
I know there is a dinosaur museum in Rockford if your kids are interested in them at all. I'm not sure what it is called though. The Clock Tower Inn in Rockford has added an indoor waterpark. I haven't stayed there since it was added but it doesn't look real big so may be a good waterpark for younger kids. I'm sure there will be pictures of it on their website. Have fun! It does seem like it is hard to find places to go that aren't in Chicago.
