Section 201 has one of the most wide open views of the field in the entire ballpark. I've sat here twice for Rangers games and have been to 100+ games since the place opened so I know where all of the best places to sit are.
The Lexus Club is great for families. Fans seem to be a little more subdued and less rowdy in these seats. Many of your young boys will probably like that these seats sit above the bullpen of whoever the Rangers are playing that night. If they want to even venture down to section 101 one level below, the ushers are usually pretty laid back about letting people take pitchers of players as they warm up in the bullpen. Before the game...not during the game.

The club concourse area is extremely nice and air conditioned; perfect for those hot summer days. The Rangers don't play a ton of day games, usually just on Thursdays and Sundays.
You're allowed to bring in your own bottled water into soft sided coolers which is a nice gesture to fans. You can keep refilling it at the water fountains. Overall, 201 is a great place to sit and Rangers Ballpark is not one you want to pass up on your quest to see all 30.
