A great stay at Hilton Chicago/Oak Brook Hills Resort & Conference Center in Oak Brook can include a round of golf at the 18-hole course. You can visit the spa to be pampered with massages, facials, or mani/pedis, and B. Restaurant and Lounge, one of 4 restaurants, serves American cuisine and is open for breakfast, lunch, and dinner. Other highlights include 2 bars/lounges, an indoor pool, and a 24-hour fitness center. The pool and room service get great marks from fellow travelers.
