We stay there every year and always park at the theatre parking ramp (eahc floor is names after a musical) on Dearborn and Lake (1-2 blocks from the hotel). It was $30 per 24 hours when we were there a few months ago in Dec 06. The $16 a day is by far a better deal, but if the weather is nasty this one is much closer for the 'driver' to have to get back to the hotel.
