So I decided yesterday I'll fly out to Chicago and checkout this whole pinball expo thing. Just coming myself. What should I expect?

I can't take time off work so I'll fly over just for the Sat/Sunday unfortunately. I'm a bit late to planning this and with the quick turn around I'm just going to stay near the airport and commute into the city.

• Is it pretty easy getting form o'hare to downtown?
• Am I going to end up buying a bunch of stuff? Should I bring an extra suit case?
• If I'm just going for Sat and the 1/2 day on Sunday should I buy a pass or just day pay?
• Are most vendors cash only or do they accept usually credit cards?
• I'm coming from Los Angeles, it's 80 degrees here today, am I going to freeze in Chicago?
• When is the ideal time to checkout the halls?
• Any other advise I should know?

Thanks for the input everyone. I booked my flight already so I'm definitely going. This will be my first show so really nothing to compare it to. It's a bummer I'll miss Friday. I especially wanted to see that Dutch Pinball update as I've been following TBL saga for years.

Sounds like I'll get one good day on Saturday and I'll make plans to do something else Sunday. Hoping there's a TBL on location as I've never seen it in person. Not sure if it would be worth the seminar pass + the $30 day daily fee just for the single day though. I'll have to think about that.
