My wife & I have been coming here to Rangers Spring Training for the past 4 years...this is the most fan-friendly park in the Cactus League. Free parking and relatively low ticket prices.
The Sundancers (volunteer ushers) are superb. They really represent the community well.
I noted several semi-positive reviews that referenced concessions. Please know that you can enter with 1 liter of water / person (I like the sparkling flavored variety) and snacks (peanuts, popcorn, pistachios, etc.) in sealed or zip lock bags.
If you are ambitious, you can pack a picnic and eat on the lawn or at you seats. On different occasions we've brought ribs, bratwurst, pulled pork, pastrami, veggies and hummus, chicken and gyros. Never had a problem with access. So if you don't want ballpark food bring your own. I only know of one other ballpark this fan-friendly in the Cactus League.
