The advantages of the infield area are that it is closer to the pitch, has a better view of the players, and has a warmer atmosphere. The grandstand section is easier to bring children to the game and is more affordable than an infield ticket.
As for which stands are best, it depends on your personal needs and preferences. 12 and 13 are both considered good choices, but it depends on which stands are closer and more convenient for you, as well as your personal preferences.
In summary, whether you choose the infield area or the grandstand area, both have their pros and cons. When choosing a location, it is recommended that you make a choice based on your needs and preferences.
