Seats on the third base side of the field get the shade first, so I would definitely recommend sitting on that side of the field. I would look to find a seat in the 400 level on this side of the field (Sections 460-478) because these are small sections that will allow you to easily get to the concourse for refreshments and they have great views from the upper level. These sections are small so any row in this area would be a good option for bringing the family.
