Awesome, thanks everyone, these are fantastic ideas. The boat tour sounds awesome, especially since the weather looks to be nice next weekend (I'll believe it when I see it). I think we'll have pizza for lunch on Friday and maybe Sunday, so we can give 2 places a try.
Scott- my conference for work (Mon-Thurs) is actually in Schaumburg, so I am going to take the L there Sunday after she leaves, and then I am staying at the Renaissance there for the week.
