Drove all the way out to the stupid mall, went to the Apple store, waited for them to get me the 5S and was in the process of activating it and because I'm a AT&T business account they couldn't do it. So I trekked up to the AT&T store and they told me I had to order one and it would be 7-14 business days. Yes, I know, first world problems but it just burned me. My iPhone is almost full and has been doing crazy shit. Must be all the porn.
Sweet JJ and his crew were kind enough to save me a 2nd row seat in left center on Opening Day & I'm pretty sure they got in line at 9:00 or 9:30 am. Not sure what time you should arrive for non homer opener games though.
Hope you enjoy vulgarity, obscenities and beer spilling all over you! Have a blast!
My biggest advice is to take the L train and walk to Wrigley. Not only is it more convenient, you get to see some of the neighborhood. I definitely recommend stopping in for a beer at one of the local watering holes. I like the Nisei Lounge or Murphy's Bleachers. It will be crowded but everything is on game day.
I don't know if you've booked your hotel yet but I'd advise one that's by a red line station so (again) you can take the train to & from the game. Are you driving to Chicago?
