When we checked, at 8:50 pm, they told us their system didn't work and to get in line and we could go in.
You are in the middle of nowhere and their restaurants were either closed or in the case of the buffet, they took our phone number to be texted and it was an hour and a half wait. When we arrived we noticed relatively few cars and now we know why. We were there over the Labor Day weekend. The food service at the casino was almost nonexistent.
