I know it's a casino so you can't expect to win every time, but after all this time going I can definitely see a decline, at least for us personally. It's not unheard of to drop $200-$300 into a machine and get absolutely nothing back, and not even bonus games.
I agree with other reviews that the payouts on the slots is getting pretty bad.
We have been going here for a few years now, and both my husband and I have maintained executive producer status so we are clearly spending a good amount of money.
