Karla Zimmerman: I'm impressed! You've already been very creative. You could try a baseball game. Both Wrigley Field and US Cellular Field offer special wheelchair seating. If your aunt likes art, you could try the Art Institute which is wheelchair accessible throughout.

San Antonio, Tex.: Hi! I'm a mom taking her 13-year-old daughter to acrobatic gymnastics National Championship in Des Moines at the end of the month. As a treat, I'm taking her and her 10-year-old sister to Chicago from July 30 to August 2. Where should we stay? We want to go to Hancock Tower on Wednesday night to see sunset and fireworks and "Wicked" on Thursday. Not really into American Girl Dolls. Would love to see appropriate art museum for budding 10-year-old artist. Would love to see cool stuff for 13-year-old...how things work...tours of big company manufacturing or TV show production. Thanks!

Karla Zimmerman: Take the budding artist to the Art Institute. Its Kraft Education Center provides activity books and programs to help kids of all ages interact with the collection. Check the museum's website under the "Families" heading for more info. As for where to stay: the Embassy Suites Downtown is popular with families.

Atlanta, Ga.: Once a HotTix Booth existed across from the Marshall Field's store on State Street in the Loop (yes, I am dating myself!). Since HotTix is no longer there (and Macy's has replaced Field's), what is the best way to get a couple of same-day, half-priced tickets to the great shows on Randolph Street's theatre district?

Karla Zimmerman: Hot Tix is still around, my friend. You can buy same-day, half-price tickets online, or at outlets at 72 E. Randolph Street and 163 E. Pearson Street. Note they're closed on Mondays.

Aiken, S.C.: Where in Chicago does one go for the best Greek food?

Karla Zimmerman: Chicago's Greektown lies along Halsted Street, just west of the Loop. You'll have lots of restaurants to choose from. I recommend Artopolis Bakery & Cafe.

Toronto, Ontario: Can you suggest a couple of hotels at each price point that's close to a subway station? I'm a female who's looking to get away solo to Chicago for a few days and would like to stay at a decent place that's not far from a station. Thanks!
