My 2 sisters & I will be going to Fox River at the end of September for one week (a 13 hour drive from home). We would like to explore the local area as well as spend 2 or 3 days in Chicago. I've done some research and the timeshare appears to be adequate for our needs (we're in a standard unit, not presidential). To get to Chicago we can drive but parking is expensive. Or we can take the Metra from Aurora but I've read that the parking lot can fill up early with business commuters. Or we can take Amtrak from Mendota which has long-term parking, allowing us to overnight in Chicago. I've never been to the area and could sure use some guidance.
