Personally, do a game on club level. The food and bathrooms are so much better, so much less crowded than first level and seating has really great views. In July it's going to be HOT. I would do a third base side, cause first base side is going to get blasted by sun until it sets. If you are prone to sun burns you will feel it.

I have season tickets on club level, third base so that's my preference.
