We stayed for one night when returning from Chicago to New York. On the way to Chicago, we stayed at the Hampton Inn. This hotel is comparable to the Hampton Inn. The room is a bit bigger at the Fairfield Inn but the bathroom is not quite as nice or as big. The linens (mentioned in other reviews) are just ok but I didn't think the linens were so hot anywhere else! The amenities provided in the bathrooms were a bit better at the hampton, if that makes a difference. The bed at the Fairfield was not as soft as at the Hampton (which was better for me). Breakfasts were comparable. Amenities in the lobby werre better at the Hampton. Decor at the Hampton was a bit better. Staff were just as nice and friendly.
If you are going for a one night stay on a road trip, I would select based on price and your "rewards" program!
