What times are the stadium tours available?
I'm not sure, I went sometime last summer on a weekday afternoon when the Reds are on the road. I do know that the Reds being on the road is key, I don't think they do them on days when there're home games. You should go though. It's pretty good. No clubhouse access (apparently they got rid of that a few years ago for security reasons), but you get to see some of the clubs and restaurants, several suites (including the owner's one), the press box (but not the broadcast booths), the Reds dugout, and you get to walk very briefly on the field, from the Reds dugout to the "center" entrance to the tunnel down the hall where the umps' suite is (you don't get to go in that though). Very good tour.
