Chicago --> Grand Canyon Road trip, things to see?

[Chaos_ult]

So this friday I'll be taking a road trip with my family to the Grand Canyon in Arizona. Having never been out of the midwest, I really don't know what to expect.

Can people give some suggestions on what to see/where to go? We plan on stopping in Colorado to camp for at least a day. Other than that we haven't even planned anything yet.

BTW, we plan on being gone for two weeks.

Any help is appreciated. Thanks in advance
