If you choose to book a stay at a 4-star hotel in Grant Park, you'll usually find loads of amenities to ensure you're comfortable, such as a pool, restaurant and gym. You can enjoy top-quality service and deluxe accommodation. Pick a 5-star hotel and you'll get a few more perks — think on-site spas, around-the-clock concierge and indulgent turndown services. You'll most likely get extra amenities and first-rate services at a 5-star retreat, though both are awesome options for luxury guests.
