Both teams are terrible this year, unfortunately.

I'm not a Cubs fan, so I don't go to many games (only when friends invite me) and I have never been to a rooftop. However, Amazon Local had a $75 rooftop deal that is probably expiring soon if you have your mind set on the rooftops.

Personally, I think the park itself isn't very good. It's gotten to be very overrated over time.
