Doing Route 66 on a budget? Camping is the move. As a route 66 RVer myself, here are some of my favorite camping options along the route. Starting from Chicago: Indiana Dunes State Park : Yes, it can feel a little tight. Sites are fairly close together and there are a lot of them. But it’s a fantastic basecamp for exploring Chicago, whether you’re tent camping or in an RV. The rail service right from the park entrance into downtown Chicago is a big win. Being able to hop on the train and skip city parking (especially with a big tow vehicle) was awesome. If you’re rolling in a bigger rig and just need a practical city-access option,  McCormick Place Lot B  is another solid choice. It’s not camping (so not tents)… think more overnight RV parking.
