Love the new park, outdoor baseball like it should be with great room and food. As others have said, very modern and fan-friendly.
I'll give a little advice on the seating:
If you are going to a night game almost any seat in the house will be good, the right field bleachers will be looking into the sun but only for a short while.
If you are going to a day game on a hot day you are better off on the 1st base line than the 3rd base line, the sun pounds the 3rd base seating and there is usually little breeze in the stadium to help cool off, one time baking there was enough.
Another option on a hot day is the Delta Sky360 Legends Club seats, which are the third section behind home plate and run from approximately first base around past third base. The great thing about Legends seats is you can access the Legends Club which is an indoors climate-controlled concourse filled with food and shops that only people with Legends tickets can access, which is much better than fighting the crowd at the regular food booths. Another thing I like about the Legends club is the row of full-length glass running along the front of it with a counter and barstools so you can sit and watch the game while eating and listening to the radio play-by-play before going back out to your seat. The downside to Legends seats is they are not sold as single-game tickets, so you have to buy them off of StubHub or a comparable site, but the prices have been fairly cheap the times I have bought them.
