We visited Chicago for 5 days in July and it was a really great place in every respect. We booked visits and shows through the concierge all of which were excellent - go on the untouchables tour and don't miss the Field museum and the art institute! The food in the Peninsula was terrific, especially recommend the Shanghai terrace. The service was polite, attentive and very helpful at every level. Room, executive suite, was spacious and well fitted out. Great location to shops, restaurants and all amenities!
