Out of towner needs advice

Hi ladies. I'm traveling to Chicago with baby and husband in a few weeks for a work convention for me at the McCormick Place Convention Center. I have the option to stay at the Hyatt connected to McCormick or a hotel near North Michigan Ave. I'm still nursing so obviously the Hyatt would be better to nurse baby and see my family  more often while I'm at the convention. However, I'm worried that the neighborhood isn't very good for my husband to go out with baby and get to downtown. We would want to avoid taxis. I'm worried he'll feel trapped by the location and also it doesn't seem like we'd be able to easily go for a quick bite.

What would you all recommend? Is the McCormick place area terrible for easy access to restaurants and stuff to do?
