How far South are you headed? There's several marina's in the Peoria area. Eastport has transient slips with shorepower and nice bath/laundry facilities. There's a Famous Daves restaurant there as well. Cross the river for dockside dining at Joes Crab Shack, Damons or Old Chicago Pizza.
Plus, it's fun to play "Dodge the Log" and "Is silt a suitable planing medium?"
