Wrigley is a nostalgic old stadium. A lot like Fenway Park. You should know what to expect when you go there.
I've been to almost every stadium in MLB, and of all the "old" stadiums, Wrigley was the best. I actually liked walking around Wrigleyville and hitting the pubs in the area.
For the record, Angel Stadium is an "old" stadium also. While it has it's charm, it's pretty old also when compared to Petco, PNC Park, Oracle Park in San Francisco and those stadiums are pretty fun.
I would have suggested taking the train in to Wrigley and avoiding the traffic.
