We are going to be at the Pheasant Run resort for 6 days, beginning Thursday. We will not have a car as we are arriving by train in to Naperville. Are there any markets/grocery stores within walking distance so we can pick up a few snacks and beverages? I know there are restaurants galore, but that can get expensive. We do have a small fridge in our room. Also, is there a shuttle or other way of getting in to Chicago for a daytrip?
