Why not wait until everyone is seated and the music has started and THEN sweep up that gum wrapper. (sweeping the lobby while people are trying to get to their seats. But, just like the casino, sometimes the janitorial staff are in the way. Oh, and unlike many concerts I have been to in other places, most of these concerts start right on time!!! And don't expect a local band as a warm up! Just like the casino, this place is nice and clean with janitorial staff always in view.
One drawback: no place to buy snacks once inside, but we've learned to get there early enough to enjoy a relaxing dinner before the show starts. Every level has a bar and they even have cocktail waiters and waitresses working the stadium. I prefer elevated seating, so I don't like the floor and at my age, I don't really need to be THAT close to the stage. I love this place! I think we have managed to sit in every section and all I can say is (with the exception of the floor seating) there's not a bad seat in the house. They host many of the bands from our younger years and it's less crowded and more intimate that the venues in DFW area. My friends and I have started attending concerts here recently.
