Rockford is major. You could chill out for a week or two here and still not see it all. If you’d like to experience as much as possible in this metropolis, a rental car is a must. Keep in mind that driving around the city usually comes with tight streets and even tighter parking spaces. Don’t stress though, because a small, economical car can make this much easier to navigate. If you’re aiming to leave the city behind you and take in some of the prairies that Rockford is well known for, you may prefer a rental car with more power and room to move. A full-size or mid-size SUV are perfect for scenic road trips.
