I agree with the idea that you should plan a different trip so you can enjoy getting to the destination and have a much more enjoyable trip.
Have you considered going to the west coast of Michigan and the Sleeping Bear Dunes? That coast has such beautiful beaches and lots of campgrounds.
Or head to the Blue Ridge Mountains....Luray Caverns in Va. Or, have you gone to the National Park at Assateague, MD? Or up to NY state to the Niagara Falls area? Or up to the Thousand Islands?
Just trying to suggest trips where you would only kill 4 days traveling and have the rest of the time to enjoy.
