I've been here a few times for Spring Training. The facility is nice enough but seems a bit dated. The seating is not the most comfortable but I have to say that the last game I took in here was awesome because we got seats not too far behind home plate in the upper section....but the best part was the it was beneath the announcer's booth and in the shade which was GREAT considering that I failed to bring sunscreen.
The concessions here are a bit limited and while I have nothing to complain about, compared to the other venues I've hit, Peoria is probably my least favorite.
