Upper Deck Box by far. No risk of having your view blocked by people constantly walking in front of you on the walkway and the view is fantastic. You're right on top of the terrace box seats, so it's not like you're further back, either. And it's much more open. No sense of being cramped under the overhang surrounded by thousands of people. It used to be a real no-brainer prior to a few years ago when UD Box seats were cheaper relative to other seating, but they've really raised the price on those seats recently. Here are a couple of examples: 418: http://www.seatdata.com/images/mlb_cubs/800x600/418.jpg 218: http://www.seatdata.com/images/mlb_cubs/800x600/218.jpg (first 3 or 4 rows, I believe) I thought it was 7 or 8 Actually, now that I think about it, I'm pretty sure it's 6. The pillars are in row 6 in the 200 level except for in the corners, so terrace box seats guarantee that you won't be obstructed...by the pillars. But if you're in the first few rows, you're going to be pretty annoyed by all of the people walking or standing in front of you on the walkway. Especially cotton candy vendors, which you don't have to deal with in the 400 level.
