I'm going to be in Chicago for work the first week of December, and yes, I know it's going to be ca-hold. I'm from KC, which isn't much better. Normally I compare distance to the work location and go from there, but for those that have been to both - is there a clear winner between the standard Marriott or Renaissance? Another option would be staying downtown and taking the L each morning and afternoon, which I'm thinking might be my best option. This isn't work that's going to start early or last into the evening. Comments welcome.
