Which way do I go?

I am going up this weekend and staying at a Mcquoids house. We are bringing a portable to go out and about. Can anybody help me on where there is a good chance of catching some Walleye or even big Perch and what are the times they are usually biting. I have people comming all the way from Chicago and Indiana, so I would like to show them a good time. You can email me at [email protected] if you can help me. Thanks
