renoel- I'd been hoping someone would respond to you, because my wife and I are also taking our girls to Chicago for Memorial Day to go to American Girl Place. I can't personally vouch for any of the places, because I've only stayed at the Drake in that area, which was nice for business, but we were looking for a suite for this trip. I just booked the Omni. If their service is half as good as the two women I just spoke to in the hotel (front desk and reservations), our stay will be a delight. Possibly two of the most helpful and pleasant hotel people I've ever dealt with (I probably have about 25 hotel stays a year- not a lot for this board...). Omni is two blocks from American Girl Place and gets 4* from AAA and Mobil (and Frommer's calls it Kid Friendly). $159 for a one bedroom suite. After investigating a lot, I would love to have stayed at Four Seasons or Ritz but just couldn't justify the cost for a suite (now if I had just needed a room for 2 people like you seem to, I might have thought about splurging ($265 per night for regular room). An interesting option for you might be to try to book LeMeridien via Priceline. (There seem to be a lot of good values being booked there if you look at www.bidingfortravel.com)but with the setup we wanted with either a suite or two connected bedrooms, I just wasn't willing to role the dice, but if I had wanted one room, I might have gone this way. Good luck. Maybe we'll see you there.
