I go to ORD a lot on business and pleasure. Truly. I feel like I live there.

I've stayed at all the hotels you mentioned. The Peninsula a is superior hotel, that happens to be on Superior street. What a coincidence. If you got a really good corporate rate, I'd stay there! Why not? It's a fine hotel, and Chicago? What a GREAT city. Especially when you will be there.

When you are in this class of hotel, you are not going to be disappointed. Any other property in this range is going to be on par, but not necessarily "better", or "worse". Just a different flavor. Since I don't know your taste, it's hard to recommend.

In this class of hotel, it's all personal taste.

I like the Intercontinental. Probably because it's right on Michigan Ave, is smaller, intimate, yet upscale and lovely. They also have a really great Starbucks off the lobby (an upscale Starbucks), and are attached to Jordon's Steak House. It's probably my favorite hotel in Chicago because of location, intimacy, appointments VS cost, and the attached coffee/restaurant choices.

Trump? Palmer House? Hilton Mag Mile? Fairmont? The list goes on. There are SO MANY good choices in Chicago we'd run out of room. By the way, I happen to like where Trump is. That section of the Mag Mile is my favorite, as it is closer to the Water Tower. But that's my preference.

Net net, I'd stay where you got your deal and look forward to it. What's NOT to like about the Peninsula?

Enjoy!
