I had booked the Omni Hotel because I wanted a suite (traveling with a small child). Thanks to trip advisor and a travel ticker special, it looks like I can get a suite at the Hard Rock for $30 less.
We're only in the city for one night (2 full days of sight seeing, taking the train in from the burbs in the morning with an evening flight the following day), and I anticipate our itinerary will include Lincoln Park or the Shedd Aquarium and an architectural boat tour (weather permitting). I'm open to recommendations on other things to do, also. On a previous trip we've visited Navy Pier, John Hancock and Millenium Park.
So I am wondering 1) if you have an opinion between the two hotels based on location. Should probably also take into consideration ease of picking up bags stored since check out to take the train to the airport also. And 2) if you have other favorite activities to do with a 4 year old.
