Easy access to casino from the interstate, long wait to get players card, cashiers were very friendly and slot attendants were everywhere. My only suggestion would be opening a cashiers cage on level two. It's a pretty long walk to get to the cages from upstairs. I smoke, and the air filtration was great. None of the haze or smell that you usually find in a casino. Loosen the slots to allow more winning and enforce the no multiple machine usage during busy times.
