For the Cubs, I'd buy tickets ASAP. Tickets will only get pricier as the season goes on. Tickets are probably still available online through the Cubs website. I believe there's a "view from seat" function when buying. If cost is a factor, pick weekday games against lesser teams. Early in the season would be cheaper too. The bleachers are general admission, the park opens two hours before game time. I recommend getting in line for the gates opening. You have a better chance of choosing your seat and you get to watch BP, with a better chance of getting a BP homerun ball. The bigger group you have, the more imperative this is. You can bring in unopened plastic bottles of non alcoholic beverages and snacks to help cut costs. If the weather is hot, its especially good to stay hydrated. There's also a discount on ballpark food, I believe for the 1st hour the park is open. I prefer day games too. The crowd is a bit less rowdy in the bleachers (less drinking before the game). Weekday games the crowd tends to be a bit older. Right field faces west so the setting sun can be in your eyes.

The first few rows of the upper deck are great seats, kind of under rated. On the lower level, I prefer not being too far back under the upper deck. You can't see fly balls until the outfielder is about to catch it nor can you see the center field scoreboard. I enjoy the lower level corner seats, they rise gradually and give a decent perspective.

I've been to hundreds of games at Wrigley and have sat in every price level and location, from the old days when the upper deck was closed to now, when the team is the reigning World Series Champion.
