So sorry we do not appear to have any available holiday cottages in Illinois at present.
May we suggest perusing alternative holiday lettings in United States?
We recommend that you try our advanced Cottage Search facility to enter your essential information such as occupancy, number of bedrooms, garden required and so on. This will create a selection of possible holiday rentals. Secondly, reduce the list by adding any other points that might be of lesser importance such as setting or type of accommodation.
